-Captain Sauce

Before episode 1
At some point, Kurt joined the X-men.

In the main series
In the first episode, Nightcrawler is seen reading a book and later on talking to Emma Frost. Since Kurt didn't get a piece of Kevin's cake, he instead cooks something with vegetables.

One episode later, he attends Kevin's party, where he dances with Gollum, Emma Watson and Wolverine. Later in the evening, while Emma Jagr and Kevin are flirting, he shouts at them about love.

Kevin Sauce
Kurt probably doesn't like Kevin, considering that he didn't get a piece of cake.

Emma Frost
The two of them appear to like each other, as they talked about art in the first episode.

Personality and Traits
Kurt seems to like reading books and discussing art, suggesting that he has a refined taste.

Trivia
He's the only member of the X-Men that didn't get a piece of Kevin's chocolate cake.
