How will the Scions change when they wake up?

[gumas]

They won't be able to move. They'll have to go into rehab to build up strengh again, which will take half the next expansion.

nah, all those rocky training to get their body back to fit condition is probably shown on the expansion CG trailer

and some of them will sport the new job

but either way we need to know whether they will finally manage to go back or not, you never know what yoshi think, he might go "okay only you you and you go back, the rest will drift in aether for eternity"
