It looks like NXT's Dominik Dijakovic is indeed involved with the new RETRIBUTION stable.
The talented big man, who hasn't been featured on the black and gold brand since he was taken out by Karrion Kross a few weeks ago, has been rumored to be a part of the faction since they debuted in spectacularly underwhelming fashion on Raw. Now, DD has sent out a since deleted Tweet which certainly seems to confirm (unless he's trolling us) that he is aligned with RETRIBUTION.
The accompanying image appears as static initially, but it's since been deciphered as saying “we are in control.”
Although it's highly unlikely that Dijakovic has actually been seen on TV with the rest of the group (he is pushing seven foot tall, and these guys... aren't), there's a pretty good chance he'll ultimately be unveiled as the mastermind or leader behind them.
This angle has been widely criticized by fans. A new stable always has a lot of potential, but the execution of their little "invasion" of WWE has been laughable so far. This week on Raw, they - wait for it now - threw a brick through a widow. The rest of the locker room must be shitting themselves.
