Thanks to Canadagraphs for the BTS photo and the SpoilerTV reader who sent this in. Rupture is also know as Armando Ramon and based off this BTS photo and following tweets, it might be so. If you think it's someone else, share your comments below.
Dropped by #TheFlash set for a bit tonight....and who is THIS?

Got 1 person suggesting its Rupture.
Which makes sense.
He was attacking Cisco & Barry
Nicholas Gonzalez is in Vancouver.
