Nightmare on Christmas - S3-E22
Continuity mistake: When Power Man is wearing White Tiger's tiara (her Christmas gift), he has it on point-side down. White Tiger grabs it with both hands and puts it on and it's now point-side up, without her flipping it. You also see it go from a partial band tiara to a fully enclosed band tiara, like a crown.
Chosen answer: He simply survived the crash without much explanation of exactly how. However, he hid from everyone after the crash to find out his truth, so everyone just thought he died. (This is common is comics where someone is presumed dead or in a situation "no one could survive" and then later shows up alive and the how isn't explained).
