Awwwwwww... - when the Commander's two young children ask to sleep in his bed after they have nightmares and slowly take up all of the room. He retreats to their bed and they follow him after they have nightmares, eventually falling asleep on top of him.
A lot of the Commander's other interactions with his kids are pretty adorable also.
While small in comparison to the other things the Commander has said, saying that he will still defend Chuck Norris' nondescript spacefuture freedom to say whatever he wants (including that said nondescript spacefuture has a stupid religion) is still heartwarming.
This moment◊, where the Commander (realising that Jared is useless as a fighter) tries to make him a part of the team (as the potion holder), is oddly heartwarming on The Commander's part.
