Brock Lesnar didn't walk out of this past Monday's episode of RAW because of anything to do with creative, but business. It is said that Lesnar was speaking to WWE about business matters concerning a new contract and that they couldn't agree on something and Lesnar decided to end the negotiations there and not appear on RAW. Lesnar has four dates left on his contract 3/9 RAW in Pittsburgh, 3/23 RAW in Los Angeles, Wrestlemania 31 and the RAW the night after. Lesnar didn't fly on a private jet of his own, but a WWE jet as they provide his travel to and from the arena. Lesnar is expected to honor his future dates and the severity of the breakdown in negotiations isn't known at this time, so nobody knows how it could impact future proceedings.
