Ambush on the street if Vicky doesn't do you after taking you to her home I believe. I can't remember the original, so can't say for sure if it's different.is it getting ambushed by RYe in the streets on the way back, or is it when Rye busts into your own apartment after a date with Vicky? I would imagine it's when Rye busts into your apartment, but given the grind of this game, and the horrible save system, I'll never know what going the Rye route meant.
BTW look one page back and you'll see posts on how to edit the save for all the money you need, stats etc. to skip the grind.
