Sometimes I feel like ppl underestimate how much Kaveh also cares about Alhaitham...ordering extra takeout during his outings just so he can bring some back for haitham, fussing & worrying abt his wellbeing during the Archon quest - he's keenly aware that alhaitham is the only person who truly sees him for who he is, faults and all.
Kaveh has never stopped caring about Alhaitham from when they first met, even after their fallout, but he was just too guilted by his own conscience then
