I just hope it's nothing ridiculous. So far we got:
S1: The Klingons, of all people, retreat just before they win the war, because someone they didn't take seriously said she'd blow up her own homeworld.
S2: The mysterious angel is someone we've known all along and the mysterious suit was developed by S31 decades ago.
S3: The big mystery disaster was caused by a crying kid.
