If Eddie's soul was sucked into the singularity... Who owns Space Ghost at the moment?
How exactly was Barry golden? His mother is dead, his father is in jail, and the woman he loves who was supposed to be his wife is actually in love with someone else. Pretty far from golden right there, especially since none of that was supposed to happen, and only did because his arch enemy went back in time to alter things for personal gain.
His father liked being in jail. An institutional Man? Or he had no interest in being separated from his boyfriend? Daddy said he was good. Hank is not a problem.
Mum has been dead for 12 years. Sad but again, Barry is good with that.
Barry has no claim to Iris, and that news paper from the future says that he's going to get there eventually, so there's no reason to rudely temporally cock-block Eddie.
The Flash's arch villain thinks of him as a son and loves him.
Meanwhile the city has not been destroyed by a tidal wave, and the planet has not been destroyed by an unstable abused singularity.
My standard for golden is pretty low.
A nonreduction of stellar bodies in our Solar System.
Besides, how time travel should work, is that when he returns to the present it will be wrong and he will have the old memories form the original time line and be completely alien to the new timeline... OR he will vanish, like Thawne did, so a different Barry will grown up in a divergent timeline having no fricking idea about the sacrifice our suicidal Barry made.
If Barry vanishes in the past, that means that his wormhole isn't there either, which is how Wells got stranded in the first place, so the wormhole cannot explode because it will have immediately never have existed as soon as Barry was never there to have made it.
Stoopid show didn't get a nerd to run their numbers.
