Tonks hoped briefly that she'd have more fun with the teenaged Harry. Since she didn't understand what had previously happened, and only saw the peace that it brought, she really didn't understand Harry's current isolative nature. To be truthful, she might not understand if he did explain to her. To be fair to Harry, it was probably just because of how she was.
Either way, Harry supplied the fake name and Tonks would go along with it as if that really was his name. "You were in a Muggle town to begin with." Reminded to the green-eyed boy idly. She smiled apologetically to Remus and shrugged. "He doesn't like traveling. And apparently, I botched up the trip."
So they were in Canada. She looked around again, hands going in her pockets. It was cold! "How long have you been here? How'd you get here?" If Harry was worried about the younger man trying to delve too deep with him, he just had to let Tonks do her nosy thing. As her hands shoved in her pockets, Tonks felt something a little odd. Oh. Shit. The timeturner. It felt..broken. But she'd deal with that later.
