I'm glad Donnie Brasco's a movie that Kat watched recently or else she wouldn't have understood her own reference. Now I think I know how Kat's memory loss curse works, but I'm not 100%. We know she can't remember more than a month back, so does that mean that with every new day, she loses a single day 31 days back? And so as long as she remains in Rosen's group, she'll always have a memory of her last 30 days in the group? Either way, despite Kat's foray into undercover work to bust her old Alpha drug pushing boyfriend Dylan, "Falling" was a quiet, somber episode that focused on the internal struggles of the team. And it didn't always work.
