Watching this again reminds (sadly) how long they stretch out these episodes. Not gonna tell you how long till Goku wakes up in all. But luckily, the story is still good in the meantime.
And as always, your predictions have been on point. Saying they save Goku as that last sliver of hope. I feel like Goku was the OG of this style, while today we have, Superman on Justice league, Blade, Avengers, etc that do the same.
