Mickey could only put up with so much belligerent behavior from Dave, then when he was attacked fought back and knocked Dave out, which he deserved. Then that soul opening talk with Drew on the bench, wow. Letting out all of the trauma he faced and how he got the scars. The request of Drew to not drink, was special, then the reaction seen by the neighbor emptying out his liquor supply, and crying. Drew was really touched. Seems like Drew has fallen in love, and is slowly coming to terms with that.
