Really, the fact he looked like Josh Groban wasn't even on his mind, though really it should be considering he was in public and could get assaulted by fans at any moment. He should really try to do something about that at some point, but that wasn't the foremost thought on his mind currently. No, he was more concerned with this girl who looked exactly like his sister. From her looks, she was a few years older than Natasha had been when she'd died, but that didn't stop him from wondering if this was a hallucination or if his sister was trying to communicate with him from beyond the grave...and across universes.
When she moved her bag, he gave her a grateful little smile. "Thank you," he replied, taking the offered seat. He closed his eyes for some moments and took a centering breath. Okay. She couldn't possibly be Natasha in body. Perhaps it was just coincidence she looked like her. But whatever the reason, he still felt a bit freaked out about this.
Opening his eyes and looking at her, he nodded a bit. "Yeah, I have." All right, so she was displaced just like him. Which he should've realized because she wasn't calling him Josh Groban. At least not out loud, anyway. "At least things have been generally quite the past couple weeks."
Well yes, all right. So he was bad at choosing a subject that didn't give away the fact he was awkward with people. And if she was Natasha, this would be the time when she'd tease him relentlessly until he became so awkward that all the two of them could do was laugh. It was incredibly eerie that this girl looked so much like his sister. And he really wished he had a picture of her here, but he would have to settle for memories.
Clearly having awkward people skills only made things that much more awkward when the person you were talking to was the mirror image of your dead sister.
