Gun X Sword/Heartwarming

Gun X Sword is heavy on the awesome and the funny, but it has some heartwarming, too.
 * In episode 4, after Wendy has risked life and limb to get Van medicine that he doesn't actually need, he finally calls her by name when he tells her good night. Awwwww. (Alternative reaction: WHY does she put up with so much crap in exchange for such minor victories?)
 * Love makes you do crazy things apparently, and she must see something good enough in him to care for him despite his outward Jerkass tendencies, and, that's even more heartwarming.
 * After his epiphany in episode 16, Van gives the cross-puzzle to Wendy and suggests that she wear it around her neck. He seems to intend it as an apology, but given the way it was used symbolically during the epiphany, it's particularly touching that he wants Wendy to have it.
 * In a later episode  Too bad that this quickly becomes a Tear Jerker.
 * In the Distant Finale,  This contrasts with episode 9, in which he refused to take the photograph of himself, Wendy, and the El Dora gang, though the El Dora V had specifically requested that Carmen bring it to him. (He claimed he didn't "need" it.)
 * last scene together, which reveals how much they do care about each other. Particularly heartwarming given her backstory. Also might count as a Tear Jerker.
 * Final episode:.
