I'm sorry but as an outsider to this whole situation, this is a total shit take. We're not talking about an underage individual who didn't know better here. Tamara is evidently a grown ass 27 year old adult woman with a neuroscience degree. She's clearly smart and capable of making her own decisions.
It doesn't matter if she was a fan, that's not an excuse to sleep with someone knowing full well they were married. It's not like she was in a position where she had no other option but that job working for Ethan that she couldn't say no. Abusing his position my ass, they're both shitty people and deserve all the flak they're getting.
