Well, now. There is a sight Spock had not intended to see. His previous assumptions about the books she carries are quite incorrect. He did not see her use her conduit device this time, nor did she appear to be rummaging around in the small bag. A transporter?

Surely not, if she's only just learning how to use a computer.

The book itself is also curious. It's not written by anyone Spock has heard of, and the binding has an air of quality to it that would be very rare and valuable indeed in his time.

"You...do not mind giving me this? I'm afraid I haven't anything to offer in exchange."
