[Chekov never saw himself when he looked at Nathan, but he recognizes that their physical similarities could be problematic for someone like Kitty who has close (but very different) relationships with both of them. Hopefully that won't be a bad thing. He doesn't want her to feel sad when she sees him.]
Good. [He likes having his hair played with. If Kitty was happier, he'd say this is the most content he's been for... how long? Months, at least.] Thank you for letting me help.
