I agree that he didn’t groom her, despite his action still being terrible.
He definitely crossed a lot of lines with the alcohol though. They might have been drinking a bit already, but Bojack supplied them with enough alcohol for Penny’s friend to give herself alcohol poisoning, and he encouraged them to drink more. Buying alcohol is quite a common thing for groomers to do though, even if it wasn’t in this case.
I have an almost identical experience, it’s a horrible and vile thing to go through. I’m sorry it happened to you too. (It always feels so pointless to say sorry for horrible trauma, I wish there was something better to say)
Yeah, everything points to the fact that Bojack would have gone through with it.
