I guess we should just be thankful he remembers to not only grab them from the 13th, but to also put those two into stasis. Then remembering to popping them into their proper worlds and time points. Which I guess brings up the question on how well did the unsundered understand the time difference between shards and what not? As Emet seemed perplexed about how G'Raha managed to turn the Crystal Tower into a time machine. Also how safe is it really for soul and mind aether to just float around in the rift? Since it read to me that any time Emet was there trying to nap he ended up very tempted to just drift away into nothingness.
