It had never occurred to Anthony that he could help Gemma, not just by conceiving a child with her but by possibly leading her to adoption. In his uncertainty and panic (not that he gave a name to what he felt) he had missed options that were available. He knew their relationship was not built to last, especially since she wasn't looking for a husband and made that quite clear to him. If or when he was going to become a father he wanted it to be conceived with love.
"That makes sense, there were a lot of people who didn't make it through the war, there are probably babies that need homes." Turning to face Sam, Anthony smiled at her, he didn't feel so helpless or lost at the moment. Even though he wasn't ready to be a father he knew that deep down he could not ignore the fact he had a child out the world. He could offer to help Gemma adopt or foster a child but he wasn't ready to procreate.
