Last night during Castle's Season 5 premiere, "After the Storm," we saw Alexis Castle as we've never seen her before —  hungover! Rick's Ivy League-bound daughter indulged in a few too many libations at her graduation party and ended up hunched over the kitchen counter the next morning with a massive headache.

So how did 18-year-old Molly Quinn prepare for the scene? Molly admits she did a bit of research, but "not how you might think," she tweeted to a fan, implying that she did not engage in any underage drinking.

Still, Molly was a good sport about the whole thing, telling her Twitter followers that she worked hard to achieve the "Yes, my head's been in a toilet look."  

We thought Molly was extremely convincing, and the messy hair and smudged mascara were pretty spot on (not that we'd know from experience or anything!).

So is it good girl gone bad for Alexis Castle? We hear those frat parties at Columbia University can get pretty crazy.

"Not the type of girl to make the same mistake 2x's. Unlike her dad :)" Molly tweeted last night after the episode.

Hmmm, we'll see about that!

Do you think Alexis is done drinking, or will she have some wild freshman nights this fall? Tell us below!
