Kevin tries to avoid contemplating certain off-limit topics, including both the end of the world (which his teacher seems obsessed with!) and his parents' relationship.

Although Kevin has never heard his parents say the word "relationship" out loud, he acknowledges that they do know a thing or two about marriage.

When Kevin confronts Cata about her relationship with Toño, among other things, he is surprised to learn that, in many ways, she is just as confused as he is.

While Cata is out on her date with Toño, Kevin lies down on his bed to spend a couple of hours of quality "teenage meditation."

In the midst of all the confusion regarding Cata and Casas, Kevin had nearly forgotten about his girlfriend, Vicky.

When Cata breaks up with Casas, Kevin's tries to take advantage of the situation by getting his friend, Fede, to ask her if she's still in love with him. However, things don't exactly go as planned.

In his eagerness to get closer to Cata, Casas asks Kevin for yet another favor. This time, will Casas be able to convince Cata to reciprocate his love?

Kevin finally musters up the courage to talk to Cata on Casas' behalf, and his rival isn't too thrilled with the results.

Kevin is shocked when Casas, the guy who stole his girlfriend, Cata, asks him for help with their relationship. Will Kevin step up to the plate?

Kevin and Fede finally reach a truce in the "war of the sexes."
