So when Robyn passed out at Al´s house...?

Probably. After what we learn about Al in the last episode, combined with the fact that he obviously is sexually attracted to Robin, put a roofie in her wine, and took off her pants, I think it's fair to say he probably did rape her.

Or maybe not, maybe he just likes drugging women he's interested in, taking off their pants, put them in his bed, and then do nothing just to *beep* with her head.

After seeing the ending, I asked myself the same question. It's highly probable, but we'll never know for sure.

"Don't like me? Then jog on, my friend."

Hard to know - but Robin does say "Why do I not feel like thanking you."

Personally, I think she is too old for him and not his type. He probably roofied her, so he could put her in his bed with her panties on and claim he was a gentleman.

Well, if he did rape her, wouldn't she have some sort of idea that something didn't feel quite right "down there"? I'm going to say no - he did not rape her.

I believe Al was Robin's fiancé. She told johno she calle off her engagement shortly after leaving Al's house. This would explain the look of dismay on Al's face when he finds Robin in the tent with Johno, why he asks Robin if she's in love and later when he asks Robin to marry him and have a baby. This is Al's attempt to get Robin back after calling off the engagement.

I'm certain he raped her. No one collapses like that from red wine. Hell, we say Robin still cognizant enough to drive after a damn-near litre of vodka. Al definitely drugged her. Al was a sociopath, and got off on demeaning others (re: his behavior to the teenage baristas at the coffee shop, his domineering personality).
