Jo looked away from Charlie so he didn't have to see the unshed tears in her eyes. She'd known that Ted was more gone than Jen was in a way. He'd been sent away, as the City did sometimes. There was a chance that he'd return, but there was also a chance that he'd return with no memories of his time here whatsoever. There was also a chance that he was just gone for good.
She'd lost people before and this wasn't the worst thing to happen to someone that she cared for. As far as she knew, it wouldn't have hurt him. He'd just be sent back to where he came from.
That made it a little easier, but it also made it harder to get that sense of closure. She did her best to shove aside comparisons to her first boyfriend. Rick had gone on a hunt and never come back. No confirmation either way of what had happened. She still wasn't entirely sure to this day and this wasn't like that. Or so she tried to tell herself. There were a lot of variables and a lot of things that she didn't know. And perhaps the hope that Ted might someday return hurt more than knowing that he was gone for good.
She looked back up to Charlie, whose arms were out. She and Charlie hadn't spent much time together so they definitely weren't on hugging terms. There was an awkward moment when Jo tried to figure out if that's what he was indicating or if she was misreading the moment. And then, finally, she stepped forward and gave him a brief hug before she loosened her grip on the wine bottle and held it out to him to take. She felt a swell of gratitude at Charlie for accepting the dinner. They didn't need to spend the whole time talking about Ted but just knowing that she was with someone who missed Ted as much as she did was a comfort. Knowing, in fact, that she didn't need to explain it to him was a very good thing indeed.
