I dunno; Saza's biggest dilemma will be which pack to join.
If she's Life Mates with King, then it'll be his pack that she goes in obviously, but I already kinda imagined her in Masao's (since the travel party to Kyushu will pretty much be all the pack members so far). >:
And oh yeah, of course! Saza wouldn't even think about it until after Masao's babies (and hers with King) have matured into adults.
