Jeremiah Reunites Bruce with His Dead Parents in this Gotham Sneak Peek

Bruce's (David Mazouz) worst nightmare is about to begin on Gotham and TV Guide has an exclusive sneak peek at Jeremiah's (Cameron Monaghan) diabolical plans in Thursday's upcoming episode, "Ace Chemicals."

Bruce finally makes it back to the Wayne Mansion (which we haven't seen all season!) only to find two very familiar looking strangers claiming to be his parents. The audience already knows that these clones are Jeremiah's creations, but Bruce doesn't realize what's really going on until he tries to get help from Alfred (Sean Pertwee) only to find that his butler/mentor is also under the pseudo-Joker's spell as well.

We know from the "Ace Chemicals" trailer that Jeremiah is planning to make Bruce relive the night his parents died in the most traumatic way possible, but where will this all end up? The footage we've seen so far indicates this next showdown will be Jeremiah's final evolution before becoming whatever Gotham's version of Batman's greatest foe will be. We know that Bruce will never be the same either.

Gotham airs Thursday at 8/7c on Fox.
