My first instinct on this was "What the actual fuck? The Old man has finally lost it..."
But the more I thought, I realised that actually there are several reasons this could be a suspension worthy thing, or all of them combining.
First off, whatever Daniel Bryan is to Vince, he knew he deserved that moment from the people on the roster. Whatever went under the bridge, Bryan was a top guy in the eyes of the fans and many of the talents. If the roster is out for a send-off, it's not clowining time, it's serious...a matter of respect. For all the talk of Vince being out of touch, he certainly knows that to Bryan, Brie, the fans and to many of the boys, this is a tragic moment... best I can equate it to is the Hillsborough tribute where a Liverpool Goalkeeper got caught laughing on camera... he was out of the club quicker than it takes to say Yes, Yes, Yes. Send offs are sacred in the WWE...if you get one, it's cos you earned it and whatever Titus' reasons, he made Vince LAUGH on a sombre moment... the sheets and smarks COULD have been all over it and said, "he's laughing at Bryan" and caused a lot of bad publicity. Happily most were "What the fuck?"
One a little more speculative, but if true a BIG indicator is... remember a while back there were a LOT of rumors around Vince's health... and in particular, his eyesight> rumors he was struggling to see and having to almost bump into people? Not saying that is true, but grabbing someone's arm is kinda something you might do if someone has those kind of issues... a lot of Vince's stuff seems very carefully put together these days, if there is some kind of sight or balance issue, then Titus grabbing him unexpectedly could have caused a problem or led people to think there is a problem. All those rumors start up again about Vince's health...and it's not a good situation for the company.
Titus also was quite vocal about his Superbowl tix this weekend and that could also feed into it... almost a "we gave you the weekend off and you pull THIS?"
Ultimately, Vince knows what Titus brings to the table in terms of good PR and the LAST thing he wants to be doing right now is taking a black talent off the road and off Wrestlemania... race is a hot button in Entertainment right now, so it's got to be somewhat serious or an accumulation of things for them to suspend him that long. It could be as someone said, simply a way of saying... "too much is slipping, sorry pal but we're making you an example, and there's loads of guys in NXT who can replace ANY of you now..."
There is a real chance however, as with the Emma situation, cooler heads will prevail in a couple of weeks and Titus will be back on the road, just jobbing out for a while or even sent to NXT. Vince is gonna realise that Titus their "dad of the year" has to go home and tell his kids why he's home for so long... and he'll probably relent at that. He can be a dick, but I doubt even Vince is that much of one... The silver lining is it could, with the right spin, lead to something good on the back end for him... Trips, Orton, Miz, have all been in that particular shithouse and ended up champions...
