Omg yes. Kaveh would be annoyed and complain about being 'a guinea pig' but because Alhaitham is good at pretty much any and everything, he definitely appreciates it in the end. And Alhaitham--he just wants to make Kaveh feel better and take care of him because he's just... that kind of partner. Quiet and unassuming in his care, definitely a man who's love language is physical touch, less overt than words.
