The Enterprise crew continued working almost continually, barely taking the time to sleep or eat. They were all aware of the time limit imposed on them by the anomaly .But that wasn't the only reason for their haste, they also desired to leave the planet as soon as possible. There was an undercurrent of dislike running throughout most of the crew, human and non-humans , against the inhabitants of the colony. Spock overheard many crewmembers' comments to each other when they thought he couldn't hear.
"—Vulcans or Romulans, they look the same to me. And I don't trust any of them—"
"These damn point ears tried to destroy the federation and now we're bringing some more in-"
"-The captain is blinded to what Vulcans really are because he's friends with one—"
Spock ignored the comments, there was no point even bothering to report them. More crew would take there place. The sentiment against Vulcans and Romulans had intensified ever since the first incident with Nero years ago and the Narada incident with Nero's destruction of Vulcan and attempt to destroy the federation had only cemented in the minds of many the evils of both races.
It wasn't only the crew that had expressed these sentiments. One of the higher-ups in Starfleet had been quoted by a reporter as saying "It's a good thing that Vulcan was destroyed, the cyst of evil that was sitting in the heart of the federation was removed. And the remaining Vulcans should be rounded up to prevent that malignant cancer from returning to destroy us all ". The official had later retracted his statement and issued a formal apology stating his words had been taken out of context, but Spock knew that his statement reflected the views of many. A lot of the federation didn't bother to make the distinction between Vulcans and Romulans. After what had happened there was too much pain and grief; to them both races were the same: evil.
The colony's inhabitants were helpful and pleasant, but none of the crew trusted them. The children that played in the corridors were treated with as much distrust as the adults. Food that was offered was declined and there was a general air of suspicion. Spock had his own misgivings about the Vulcans in the colony, and a part of him wondered was it a by-product of being around the other crew and unconsciously picking up their sentiments, or a real feeling based on something he subconsciously detected.
He had no way to be sure which, so he tried to push away the illogical thought and focus on his tasks.
