Lee felt he had the right to be trusting, considering Tenten's body had never really left his sight. She had not screamed for help or out of anger, nor had she reacted differently other than the explosion of weaponry seals. The only thing was perhaps that she had been more quiet and guarded but they had been on a mission, after all...

Kirigakure. Lee had an acquaintance or two from there but he didn't feel confident that this stranger was someone he could trust on merit. It may have been a strategic switch just as much as a random one. Or the person could be lying about themselves altogether. Aliases were not uncommon among shinobi.

Taking everything the man said with a grain of salt, Lee remained on the defensive. "How am I to know you are not just trying to steal Tenten's body away for experimentation now that her mind it gone?"

He was worried about Tenten's actual self in another's body, but she was capable.
