Only cause Lucky has no claim to Cam
I could see Nik being the one to go all Cassadine and try to get Cam even though it means keeping him away from Jake
Lucky can keep Jake as he is the father of record. He has no right to Cam
So maybe Nik will go after Cam to give Spencer a playmate and because he wants a piece of Liz to hang onto too
he won't want Jake cause he knows he is "jason's "
zander is dead and no threat to him

or maybe steven is the one who goes after the boys
so steven ends up with cam
and jake ends up with lucky
so jason backs Lucky just to keep the boys together
