Well, it is not like it would be the first time Lesnar and WWE meet each other in a court room. They did this over the course of several years.
And it's not like Lesnar and Taker are friends, atleast they didn't use to be. For example
starting at the 6 minute mark
Plus, there are several interviews in which Lesnar didn't talk very positively about WWE.
Anyway, I just thought Lesnar shooting on Taker at WM is quite an interesting thought.
