I love how Jimmy went, "wait...what?" not just once. Jimmy's red-faced reaction was just too hilarious!
I also love how Nicole remembered so many details from that night - the corn chips and cheese, the video game. So she really was into him at the time. You don't care to remember if you don't care. Such a cute confession.
Guess this proves how easy it is to confess such things when one's in a stable relationship.
