Over that time, Mr. Immortal would develop a loving relationship with his teammate, Dinah Soar, as he was also the only one who could understand her language. It is revealed that they are soulmates, and he was her ageless-love, as she herself also possessed a degree of immortality. In the 2004 "Avengers Disassembled" storyline, Craig comes close to quitting the team, but changes his mind by the end of that storyline. In their following outing against Maelstrom, Dinah Soar is killed and Deathurge appears to take her away to the afterlife, truly terminating his and Mr. Immortal's former "friendship". Mr. Immortal would meet Deathurge again at Dinah Soar's funeral, where Deathurge expressed his regret, showing that he had truly come to love Mr. Immortal like a son. Mr. Immortal, however, is enraged at Deathurge, having taken away all that Mr. Immortal had ever cared about, and attacks Deathurge, to no avail. Craig then falls into a deep depression, repeatedly getting drunk and killing himself inside GLA headquarters while wearing a Dinah Soar "costume", as the others watch. He is later killed by Leather Boy, who infiltrated the team's headquarters disguised as Doctor Doom and killed Monkey Joe, Squirrel Girl's sidekick.
