The man's accent is unfamiliar, and he's dressed in civilian clothing, not the clothing of Starfleet, which Simon supposes makes him another of the people brought here from their own time and place by this mysterious entity called Q.

"I ... suppose I am," Simon agrees, his voice a touch rueful in a way he suspects his new companion -- colleague, rather -- will understand. After all, none of those who've been brought here had any choice in the matter, at least, not to Simon's knowledge. Perhaps not all of them have reasons to want to be home as compelling as Simon's need to care for his sister, but they must all have a place to be and people they miss.

Simon, slightly formal as always when meeting new people, steps forward to shake the man's hand.

"Simon Tam. I'm, uh, I'm a surgeon."
