It would make sense that they'd both had so much tying them to the Enterprise and thus to each other. Deanna had felt that tug when Thomas had left for another posting, yet another version of the man she loved who had placed a career over her. And yet, hadn't she more or less done the same in that instance? It was hard to sort out while it was happening and now so many years had gone by that Deanna wasn't sure how to begin to sort it all out. Maybe she didn't need to anymore. She and Will were happy and that was all that mattered.
If she knew what he was thinking, she would be quick to reassure him. Having children was something she very much wanted, even with the uncertainty of their new posting on the Titan. Ian Andrew Troi II had been as much her child as any biological one and even though the circumstances of his birth had been unknown at first, she had felt a maternal pull towards him. His life, his death, had been so quick and sudden that she'd barely had time to properly register what was happening, let alone how to handle it. And while enough time had passed that she didn't look back on it with sorrow, she thought she might be able to manage being a proper mother someday.
Someday, but not here, not in a prison.
Besides that, she knew her mother would never let her live it down if she didn't have at least one other child. Lwaxana was always going on about grandchildren. The faster they had at least one, the happier she would be and the quicker she would get off Deanna's back about it. But that could be dealt with later. Right now, she focused on what her husband was saying. It made sense and maybe if they both had something to do and focus on, they could manage better.
So she nodded firmly in response. "All right. If one of us isn't back by the end of the day, we'll use this--" She tapped her headset communicator. "--to try to contact each other." Hopefully it wouldn't come to that, but at this point it would be worth mentioning every contingency plan.
