Anthony Edward Stark

When has he not marinated in anger? When has calm ever come without an effort of will? These things predate even Hulk, and the silence is jarring for the space of a breath before there is nothing important in his world beyond Kiara and the children he'll father with her.

It's an easy enough switch to flip when the other noise is gone, and more than a decade of celibacy brings with it an intensity that Kiara doesn't even need to stoke. He has wanted children, and while he has some very big buts to that, they're even more easily subdued than Hulk.

He has no idea how many hours pass before he can think again after the most vigorous and protracted sex of his life. He's shaky and drained, both literally and figuratively, and oddly calm about getting up to retrieve the knife and vials to complete their devil's deal.

This definitely isn't how he pictured fatherhood.
