I feel like H's choices' of Abilities is incongruous with his character. He seemed since he arrived, so extremely confident in his power as a Ten-spiked Dalki with the Blade Ability; that I would never seen him copying the Regeneration Ability (since getting hurt helps him get stronger and evolve + never expecting to get hurt more than a scratch) and much less what seems a 'if I die I'm taking you down with me' kind of Ability (that would mean he thought there was a good chance he would die).
I have totally been thinking his last ability was second chance like Hilston but his words implies more of a double edge sword. Also someone correct me if I am wrong but Graham's healing didn't seem to impact his power boost and he even made a machine to help Dalki evolve by hurting and healing them.
