I know we found out about the baby not being his, but I meant more like Matt's sudden friendliness with Mohinder and adoption of Molly. I understand the adoption since Matt and Molly have been friendly from the moment he rescued her, but still, it seemed vague.
I agree though about D.L's death being sad, I really liked him tbh. I liked the inclusion of Damon Monica and Nana in the episode, just a nice quick scene.
