Heartwarming / Angel Dog

• Cooper in general. He wanders into the lives of the grieving to provide them with comfort and a reason for a fresh start.
• Jake training Cooper to get in the van, and eventually succeeding. Doubles as a Moment of Awesome.
• Everything about Jake's relationship with Cooper. Everything.
• Bobbie and Seth willingly allowing Jake to keep Cooper.
• Jake adopting a puppy at the end, which he names "Hank", presumably after the name Bobbie and Seth gave to Cooper when they met him.
