Kevin's attitude changes when he realizes Blanka didn't get it. 

-You really can be boring sometimes, he said with a really tired look.

-I think I could eat you if you were more intelligent to realize my little perverted joke. Maybe it wasn't a joke after all. I think its the same if you do it with women or men, he says with a bit serious face.

Kevin hasn't never even been in a relationship, so maybe he isn't the right person to talk about things like that.

Even though Kevin is drunk, he is a bit jealous to Blanka. No one has ever noticed him, and during that time, everyone have always been around Blanka.
