dustins non-angel

me and my husband are having a debate,and need it resolved. during the credits you see Dustin pick up a girl at a bar upon tank's fathers suggestion. the girl then dumps her purse full of dildos out on his bed, then he dumps his bate crate out over her dildos and they begin to make out before the cut to black. my husband is of the opinion that the girl in that scene is alexis's roommate ami played by lizzi caplan, while i agree it does look like her based on the circumstances of their meeting and her dialogue i believe it is a different character all together. the cast listed on imdb was not clear on this. hoping someone can shed some light on this topic.
