The next time Blake and Emma are having lunch together, Blake has the same kind of salad, but without nuts. Emma notices, and asks Blake why she doesn't have nuts. Blake gets a bit evasive, and Emma realizes that Blake must have purposefully ordered the salad without nuts. Emma says Blake doesn't have to stop eating nuts on Emma's behalf, joking that it's not like they're going to kiss or anything.
Blake looks sheepish and admits that she actually has a crush on Emma, so Blake decided to stop eating nuts just in case they DO ever kiss. Emma is charmed, and says Blake's sacrifice shouldn't be in vain. Blake hesitates, but Emma assures Blake that she really wants to kiss her. They kiss, which then leads to having sex right there in the office... best lunch break ever!
