i think it wasn't very clear in the prequels (or more precisely, sequels) of this, that bucky was part of their monogamy too. i didn't forget about him, no, but i wasn't quite sure then as to how i should include him in their tragedies. in my opinion, bucky would be terrified at the prospect of having a child. the unborn child reminded him of what he used to be, under hydra's reign, and he was afraid of losing control, of harming an innocent soul again.

the pregnancy mentioned in this story was the first one. the child's full name was joseph george rogers-barnes stark.
