Hearing Gideon say that he was going to have a child was terrifying enough. They both knew, and he at least had come to accept that they'd never have children. Die young men in battle with nothing to hold their places in history beyond dates in a history book and a name on a family tree - stilted branches with no leaves of their own. He understood this, even came to accept this back home - back in his own war.
Yet here, now in this strange place and moment that was not so. A girl, a young woman her mother's age was his - and she too had to fight. Fabian knew the Carrow siblings, young impedtuous things that even as young adults knew their way around a wand. Now they were clearly grown, and still fighting children without mercy. His child, their child and he would never know.
He didn't ask, he didn't even apologize when he stepped forward and drew Hestia against him. He wasn't going to cry, it was too much of a shock to take in, too much information to process but he woman he had cared about deeply as a teen, and now a grown woman was hurting and he could do nothing to help.
The kids outside made sense now, if they were Megan's co-conspirators they would want to keep watch, to protect their friend in a time like this. He'd do the same for Alastor or Gideon, he'd stand guard for Hestia. But that meant that they had fought as well - and Fabian realized how incredibly selfish he had been. There was a second war, and he was still fighting his own here. He had a child, and had failed her before she was even born. "I don't know what to say." Fabian admitted, kissing the top of Hestia's head. He didn't think he loved her, not yet but clearly they became something in the short time he had left, and he owed much more than a few useless words to that.
