Every time she talked about one of those details she was asked whose idea it was, and the answer was always the same.
"Ryan. Ryan. Ryan. Ryan. Ryan. Ryan," said Allegra Dahlquist.
Hare, 19, is charged with first-degree murder in the death of 18-year-old Silliman in December, 2008.
Police have implicated Dahlquist and two other teens in the murder: Aadil Shaaid Kahn, 18, and Drew Logan Shaw, 18.
Sheriff's investigators found Silliman's body on the bathroom floor of an empty mobile home near New Hill in southwestern Wake County on December 3, 2008. According to the medical examiner, the Eagle Scout was drugged and suffocated.
Prosecutors charge that Hare masterminded Silliman's death because he was angry that his girlfriend - Dahlquist - had a relationship with Silliman. The defense says Hare is not guilty of first-degree murder, but took part in a bizarre assisted suicide.
After Dahlquist finished testifying Thursday morning, prosecutors called Amber Howell to the stand.
She said she and Drew Shaw are like brother and sister.
Shaw is accused of being one of the teens who helped kill Silliman, but he was not with the group on November 25, 2008 during a first attempt to kill Silliman.
Instead, he was with Howell who said Ryan Hare kept calling Shaw and yelling at him - telling him Hare needed his help.
"Drew told him on multiple occasions, 'I don't want to have anything to do with what you guys are planning,'" Howell testified.
Howell said Shaw told her that hare had a plan to "take care of this kid he's got a thing against." Howell said she thought he meant he wanted to beat a kid up.
A week later, investigators found Silliman's body at the mobile home owned by Dahlquist's family. He was in a sleeping bag with a plastic bag over his head, his mouth duct taped shut and plastic tie wraps around his wrists and ankles.
Howell said she now regrets the advice she gave Drew Shaw.
"I told him, 'The next time Ryan calls why don't you tell him to man up and do it himself if this kid is such a problem for him,'" said Howell. "I had no idea that Mr. Hare intended to kill Mr. Silliman."
