Trisha was Oliver's girlfriend who also slept with Ben while they were briefly broken up.
Trisha dated Oliver for a while. They broke up when Oliver gave her a birthday gift that he'd purchased for an old girlfriend, forgetting that he'd had it personalized.
Sleeping with BenEdit
After breaking up with Oliver, Trisha slept with Ben on his wedding anniversary because he was upset about that and she was upset about her break-up from Oliver.
Oliver and Trisha got back together when she came to the diner and overheard him saying that she was great, not knowing that he'd seen her reflection in a water glass. Oliver then invited Trisha to go out to the family cabin with him on their trip. While they were there, Oliver discovered a pregnancy test and they speculated over who was pregnant. Both Oliver and Ben panicked about the possibility that it was Trisha's and they didn't know which of them was the father.
The two of them tried to push Trisha into doing something that indicated she wasn't pregnant, like drinking wine, but the truth didn't come out until she said she knew why they were so upset and believed it was because Oliver had found out that she slept with Ben during their break-up. That did upset Oliver, but they were both relieved to learn that she wasn't pregnant.
