i think there is a little foreshadowing going on with CJ holding Nicholas in the chopper.
In a former chapter we heard
Saul asking
Victor to take over fatherhood of his baby, should he not live, but now we have a motherly void.
i can see the "it takes a village" theme play out, with
Kelly,
Pegs,
Tanya, etc taking turns watching Nicholas, but as far as companionship goes for Saul, i can see them (CJ) eventually getting together. i can almost guarantee NOT in the actual storytelling but leaving it open for the possibility and a mutual attraction.
