Corrected entry: Will says that because of spending Christmas with Marcus he met Rachel on New Year's Eve. Between those times, Marcus meets Ellie at school. This is kind of strange, as there is no school between Christmas and New Year's Eve.

Correction: Marcus had a crush on Ellie for quite a while before Will mentioned it, as you can see by the way he looks at her in previous scenes. It is quite likely that Marcus just did not mention it to Will until Christmas time.
