Abby hadn't exactly intended to make things awkward for them; the words had slipped out before she really thought too much about them. She looked down to her teacup, bringing it up for a sip, finishing it off and pouring herself another cup.
"The last thing I want to do is force somebody out with my arrival," she replied. "I- I know what it is to be alone, to be sent away knowing that you'll never see your loved ones again. I don't mean to sound patronizing or anything. I just- well, I only mean to say is that I know the feeling and I wouldn't wish it on anybody else."
Abby looked up as Rena mentioned a sister. She hadn't known, and she looked back down as she poured a little milk in her tea. She had been lucky, she knew, to find her sister all these years after losing her. "That was my first worry," she admitted a moment later, not quite able to meet Rena's gaze. "When Thomas found me. I was so sure that he would have moved on- I mean, so much changes in ten years. And seeing you and Bridget together- I hadn't known that she was his- ours- and I thought- I didn't want to ruin whatever family you all had built up."
