You were helping the Baudelaire's out, being one of Violet's close friends. Klaus had always had a crush on you before the incident of the fire, but it was always from a distant.

Well you and Klaus were sitting together since Violet had to take Sunny to the store to get some food. Klaus was just telling you some facts, you weren't really listening, but occasionally he said something interesting. He was a total nerd, but it was kinda cute.
