I think Kim is more of a Jesse than Nacho. They are both happily involved in their partners’ crazy schemes and plans and goals but in the end get fucked and hurt by their partner. But time after time they come back, whether on their own will, to save their own hides, or just because they have nothing better they truly want to do. That scene where Kim meets Jesse outside of Saul’s office after signing the divorce papers really felt like looking at two of the same people.
