Johnny nods, and shifts around nearer the TARDIS, sitting cross-legged before them, wanting to be close to both of them if he can. The more he manages to calm down, feeling relieved and protected, the more his nerves are replaced with intense curiosity about what he's just stumbled into. He really had no idea they knew each other, arguably the two most important people he's met so far. He's happy he can see them both at the same time, though he feels a little awkward too, like he's interrupting.

He draws a couple deep breaths and lets them out slowly, gradually calming himself down. He's fine now. Everything is okay.

"I'm really glad to see you both," he murmurs, pulling away slightly to glance between them. "So, uh." He smiles faintly, not sure how to ask this. "Hhhow do you two know each other?"
