Spock's eyebrow went up in the closest thing he was ever likely to get to an expression of surprise. "The Captain is here? Curious. May I ask how long ago this network post was?"
Definitely curious given he had been speaking to Captain Kirk less than an hour before he woke up in this place and she seemed to be implying this was further back than that. There were possible explanations as to how someone could be in two places at once but it was still curious.
"Indeed? It would be fascinating to meet them. It does seem that the people behind this place have few restrictions when it comes to tampering with the time lines. It does make me curious as to whether they are aware of the consequences or simply do not care."
If it was the latter then they were wrong to call themselves scientists but then again the Klingons were as careless with the time lines in their attempts at retroactive change. Not that he would generally classify many Klingons as scientists.
