Albert is not gifted with the Force, but he does pick up on the slight change in the other man as they work, something hinting to him that Obi-Wan is thinking back onto some past event, some memory.

"A nickel for your thoughts?" He prompts, after Obi-Wan presses that kiss to his lips and Albert thinks he feels that yearning even more strongly. He doesn't know what it is, he doesn't think it's for sex, but he would like to know what is on his partner's mind, if Obi-Wan will share it.
