Spock is not surprised when he finds himself roaming the busy streets of the past. It's not like this is his first time accidentally time travelling.

The first order of business is to figure out what period he's in. Spock grabs a newspaper and looks for the date. It seems he's temporarily stuck in the early twenty-first century. The second order of business is to figure out how to return to the twenty-third century. However, that will be difficult, considering neither Kirk nor Bones are anywhere in sight. Spock is on his own this time.

"Interesting," he mutters, putting the newspaper back.
