Plot hole: After Steven breaks out of prison, he goes to Jason's home. Then Jessica's boyfriend shows up talking on the phone and he says he will ask Jessica for permission to shoot their show at Jason's house. He should know that Jessica doesn't know she is a relative of Jason.
Plot hole: It appears no one even did the slightest bit of police work in the murder of Jessica's mother, if they had they would have seen evidence that Steve's story was true. Like evidence of someone going out the window and the cop's fingerprints on the knife.
Answer: Of course he would be reborn exactly like he was before he was blown apart. Which is why he needed a blood relative to do so.
