Mark and Xavier don't see each other very often, since Mark lives in a different city while Xavier alternates between his parents' place and his college dorm. However, they get together around Christmas or summer time, and manage to get some brother stuff done. Talking about bands, sports, sex. Xavier asks how Chance is doing, Mark asks how Malcolm is doing.

Here, Xavier is talking about the Lil Wayne show he went to see, and Mark is questioning whether they are truly related or not.
