is. Additionally, Nathan seems a bit more together career-wise than S1E1 Lawrence, no? Like isn't he part-owner of that barbershop or something?

I see them as so, so, different.

But most importantly in the way Lawrence actually loved Issa, flaws and all, whereas Nathan is (understandably, based on Issa's mixed signals) cautious and seems to just be consenting to some casual relations.

I give Nathan credit for vocalizing his caution tho, I'm glad they had that conversation.
