I guess this is more of a follow-up question to the previous one, but something was brought up that I didn't consider. Mama and Papa Gresley still trust humans even after going through such a horrific incident. Which, and I'm assuming here, probably means they support what Scotsman is doing, correct?
I mean, think about it. Nobody would or should blame them for any sort of hesitation or distance. They lost their KIDS for Pete's sake! Yet they still trust humans.
(and don't forget Mama Gresley lost her limbs because of humans)
They do support Scott a lot, yes they are very traumatized by everything that has happened, even though many bad things happen to them because of humans there was also a bunch of good too.
They see the ability of Scott and how much he was able to make things better make others connect together, why wouldn't they support their son making a better place for everyone..... A better place that their lost children would have loved.
