#3. Why wasn't Brock Lesnar at Raw?

So, we still don't have a conclusive answer for this, was Brock Lesnar's absence from last week's Raw a work, in order to get Roman over and make Brock the villain. Or was it part of Brock's ongoing contract negotiations with him walking out a power-play. Or was Lesnar sent home for the photo with Dana White that Dana posted on Twitter.
However, I personally feel that this is all part of the storyline with the WWE weaving the very real contract negotiations and possible MMA return for Lesnar into their fictional narrative for Roman Reign's big 'Mania moment three years in the making.
Something that further strengthens this is the actions of Brock at the live event in Chicago with the 'Beast Incarnate' getting heat for putting Kane away in under a minute, upsetting the live crowd. This could all be part of the same effort to get people to boo for Brock, as Dave Meltzer indicated the squash match was a WWE decision.
