In "Old Man Logan", the Hulk is a villain and has an entire clan of children & grand-children. During the fight with Logan near the end, Bruce Banner says the following:
Bruce: A lot of folks say that I went mad. That the radiation sickness did something to my brain. But who else was I gonna mate with besides my first cousin? Jenny She-Hulk was the only woman out there who could take the damn pace!
Later after the battle, the clan is down to three individuals - Hulk, his baby son (Bruce Jr.) and his grown grandson Billy-Bob. When Billy-Bob questions the future of the clan now, Hulk responds with:
By "women from Heff's", he's referring to the local whorehouse shown earlier in the book, which is populated by solely human women.
Don't these two statements contradict each other? If She-Hulk was the only female who could survive mating with Hulk, how does having access to human women help?
