A bit later, when there is not the question of whether Sherlock can accompany her unnoticed, Tony finds a door and in they go.
Other Sherlock - whether this is their other Sherlock or some other other Sherlock, Bell cannot be immediately sure - is in the main bar area. Bell waves!
Also he comes over to distribute hugs to all three of them.
Hugs are nice and Bell approves. When her hands are free, she catches one of her Sherlock's with one of hers, because handholding is also nice. "How're you doing?" she asks Other Sherlock.
"...Sorry," he says, blinking, "is there a reason you're not having sex yet?"
"Because... she doesn't... want to...?" He looks at Bell. "Wait, do you?"
"I'm very sorry," he says. "Overly personal question. I ought to've known better."
Bell puts her forehead on her Sherlock's shoulder. "Well," she says.
"Help me out here," says Tony. "Is this a conversation we should be having, or should we all forget it never happened and go get hot chocolate?"
"Okay then. We can have it. Hot chocolate also sounds really good though."
"So, this is awkward," remarks Bell, squeezing her Sherlock's hand hard and making no eye contact with anyone.
"Yep," Tony agrees. "I think we should all get hot chocolate and then go somewhere. Like back home. Or somebody's room."
They get hot chocolate. They go to Bell's room.
She looks at her mug, and takes a sip, and then pulls her recorder out of her pocket and mutters an authorization to it and hands it to Sherlock and looks at her mug again.
"So, you probably know this by now, but I really like you," he says.
