Crazy ERP with kids aside.... -_-! 'shudder'... I can see it being a interesting plot twist for MSQ at some point, like u arrive to save a town/outpost/village to only find 1 child as the sole survivor sure they stay with the Scion's but see u as their savior/caretaker, could see 1 MSQ cutsciene now:
Child 1: my dad/mom's better then u'rs!
U'r Kid: no way mines better!
Child 1: my dad/mom's 'random high class rich job'
U'r Kid: Mines the WoL! >.< so there
Shadowy Garlean agent: Is that so...
