Why can’t Sasha just say it was a random guy?

Women have ONSs all the time. She could fix everything and get Tracy and Cody off her back by simply saying:

“I don’t know who it was. It was consensual but I was super drunk and he was too. He said he was in PC for business. For all I know he was married.”

The show wants Jason and Sasha. I get it. But her behavior is not endearing her to the audience and this is all completely unnecessary. Why not just have her privately confide in Jason that it’s Michael’s and they bond organically???
