From what i can tell from the promo, girder comes back possibley with some sort of electrical based ability judging from A, his glowing eyes and B the flickering lights when he breaks out of what appears to be a fridge. Personally i hope he doesnt come back as a full blown metal Grundy-like-zombe as Girder is one of my favourite non-speedster characters, and i would hate to see him become a mindless hulk rip-off. It would be cool if the particle accelerator not only ressurected him but altered his abilities, such as being trapped in his metal form (like in the comics) whilst supplementing his strength. But judging from the ep description one can assume hes suffering from either amnesia or severly degraded cognitive function, which is why he would be 'tracing his steps before he died'' as he is trying to remember who he is/was.

On the where in the hell is barry subject i think he very well may be trapped either in A some sort of speed force constructed limbo or B he is in the actual speed force or C he is in the speedster afterlife/heaven.

If hes trapped in a limbo then the notion of joe being the disguise for the speed force reaper the Black flash would make sense, as barry is in limbo trying to get out the reaper needs some way of convincing him to stat.

If he is in the speed force then joe would by a speed force construct, for what reason its keeping him trapped im not sure.

If barry is in the speedster afterlife/heaven then that would mean he is dead but the speedforce moved him to  different plane/dimension to protect him and refuses to return him back to E-1 as that would put him back in jeopardy which the speedforce has had enough of.

For a prediction; Barry is being held prisoner by the speed force and needs to either convince it to let him go or he needs to overcome some kind of emotional burden/drawback to regain his speed more powerful than ever and escape by jumping dimensions just in time to save everyone from the grundy-like-girder chasing iris around S.T.A.R. Labs.
