The defence lawyer for rugby player Paddy Jackson is continuing his summing up of the case for the jury at Belfast Crown Court today.
Brendan Kelly QC said that there was no sign that the other girls at the party would have done anything other than help the alleged victim if they witnessed a rape.
"(The alleged victim) confirmed that the girls had been nice to her downstairs. There was no suggestion made by (the woman) that they would do something other than help a girl of her age in those circumstances," he said.
Mr Kelly added: "There was no sign from their behaviour that night that they would do anything other than help her if they witnessed her being raped. The backdrop is not a form of animosity."
He also said that the witness who walked in on the woman engaged in sexual activity with Jackson and co-accused Stuart Olding, had no phone at the time.
"[She] had no telephone in her hand at the door. There were no pictures being taken at the door," he said.
Mr Kelly said the witness was central to the case.
[She] confirmed from what she could see (the woman) was not distressed. [The witness] was not stupid. She was articulate. She spoke clearly," said Mr Kelly.
He added: "[Her] evidence is extraordinary. In she walked and that was her conclusion."
Referring to the witness's evidence that Jackson asked her if she wanted to join in Mr Kelly said: "What did they do to conceal (the rape)?"
He added: "When people commit crime they tend to hide, they tend to conceal what they did because they don't want to get caught.
"What did these two violent rapists do when she walked in? They invited her to join in. [The witness] is absolutely central to this case."
Paddy Jackson (26), from Oakleigh Park, in Belfast, and Stuart Olding (24) from Ardenlee Street, in the city, deny raping the same woman. Jackson denies a further charge of sexual assault.
Blane McIlroy (26) from Royal Lodge Road, Belfast, denies exposure while Rory Harrison (25) from Manse Road, Belfast, denies perverting the course of justice and withholding information.
Referring to the prosecution case that co-accused Blane McIlroy delivered Stuart Olding's "lines" to police about what happened that night Mr Kelly said it was "complete nonsense".
"There is no possibility of the theory that's clutched at by the Crown holding any water," he added.
He reminded the jury about the woman's comments that she felt humiliated and mortified after the rape.
"Is that not something you would feel if what had happened was group sex and you had been identified in the course of it?" he asked.
Mr Kelly told the jury that the woman had been "petrified" that the sexual activity with Jackson and Olding would end up on social media.
"It was her main concern the morning after and in the days that followed. If it is your main concern why not tell a single friend?" he said.
The lawyer said she told her friend she had been raped in case an "exposé" made its way onto social media.
"If it did get out on social media, this exposé with this well known rugby player, one of the first persons to find out would be [her friend].
"So what do you do if you are trying to derail those rumours? You get in first, as soon as you wake that morning and your first port of call is [her friend]," he said.
Mr Kelly told the jury that after the woman told her friends she had been raped "she was stuck".
Mr Kelly also claimed that the police notes in this case were a "shambles".
He referred to the alleged victim's omission in her first police interview that the witness had walked in on the sexual activity and was asked by Jackson if she wanted to join in.
"It was absolutely vital that from that ABE (Achieving Best Evidence) what was missing was the independent witness walking in. It was the reason for the lie, the reason she was petrified this would end up on social media," Mr Kelly said.
He added: "There's real doubt as to when it was that the independent witness and what she had to say was first mentioned to police."
He told the jury there was doubt over "when it was, why it was and how it was (the alleged victim) finally told the police 'by the way, someone did come in."'
Mr Kelly criticised the way in which the ABE interviews were conducted by police, referring to how inconsistencies in the alleged victim's account were handled.
"If you come across significant inconsistencies then you would go back and you might re-interview. For some reason that wasn't done.
"It would appear the reason was because that particular rule is something that didn't apply or something which the particular officer was unsure," the lawyer said.
He added that there is no forensic evidence linking Jackson to penile rape.
Mr Kelly also told the jury that the woman's failure to tell doctors during her initial medical examination that she had performed a sex act on Jackson meant that no swabs were taken from her mouth.
The lawyer reminded the jury of the prosecution's suggestion that the four defendants had concocted a story to tell police.
"It's some plan these four have contrived to mislead the police, to mislead you.
"You decide whether or not the crown have stretched their evidence in that regard," he said.
Mr Kelly told the jury that Jackson had not been obliged to give evidence to the court in his own defence but he chose to do so.
"A defendant need play no part in a criminal trial. Some defendants choose to give evidence.
"In this case Mr Jackson and his co-defendants have all given evidence. No one has hidden. No one has tried to conceal. Everyone has got up, with their good character, and given their account," he said.
The lawyer said there had been some criticism over how the jury was told about Jackson's sporting background.
"You the jury don't just judge him by 27/28 of June. You want to know as much about him as possible.
"He's not looking for special treatment. That's never been his pitch ever," he said.
Mr Kelly added that everyone in the witness box is asked about their job.
"He's not asking for favours that he had been to Methody (college). It is his counsel that deems what is put before a jury.
"Don't fall into 'is he trying to play the rugby card'. He's not. The fact he played for Ireland - so what?"
He continued: "When you look over to the dock you see four men. It don't look great does it? Don't hold it against them where they came from."
Mr Kelly reminded the jury about two character witnesses who described Jackson as "placid" and a "likeable lad with no self importance".
"We have got this headline of rugby player every day. Rugby rape. But you scratch the surface of this man Paddy Jackson you start to see a bit more. You get to see what he is. I'm not painting him as a saint. You have got to look clearly at the evidence," he said.
"We are not seeking any form of special treatment. Look at him. He may well be void of vanity. Look at him," the lawyer added.
He referred to CCTV footage outside Ollies nightclub which showed Jackson standing with his hands in his pockets.
"The person you look at there is half an hour later turned into a marauding rapist," said Mr Kelly.
Mr Kelly asked the jury not to be distracted by headlines.
He continued: "The question is, does the quality of this evidence with its untruths and central inconsistencies, does it deserve a conviction of this gravity?
"Twenty months of his (Jackson's) life have been blighted by evidence of this poor quality. Each time evidence was checked, each time evidence came from a video or other source, the complainant's account fell," he said.
Mr Kelly concluded his summing up of the evidence. The case was adjourned until Wednesday.
The judge told the jury to put the case out of their minds until then.
At hearing.
