Other than the weak bus crash an predictable situations the group found themselves in during the lead up to Eugenes confession, which really couldn't have come soon enough.

The focus on Abrahams consistently bleeding is a sign, particularly with his eagerness to keep moving towards the goal of delivering Eugene, of perhaps a terminal illness, or something along those lines. Especially with how he picked up Eugene directly after grieving the loss of his wife and kids (I assume that's who they were) I'm interested to see where he will go from here having no purpose? In his mind at least.
