Despite the fact that EC3 was being pushed as a top star in those video packages WWE was airing a few months back, we've seen nothing of him on RAW since that loss to Dean Ambrose and he's only been shown backstage (as a mute) or losing to jobbers on Main Event.
Now, after WWE wished him a happy birthday, EC3 had the perfect response by pointing out the fact he's been sitting in catering.
After a successful run in TNA, EC3 made the leap to WWE and made his NXT debut last January. After several months of working there, he was called up but, as mentioned above, has done little to nothing since. With reports swirling that Vince McMahon isn't happy with him, it's hard to say if we'll ever see him do anything significant in the near future.
