Mark writes that blink were supposed to close every show even though they were co-headliners, and writes in general about how difficult a tour of that size is to manage because of lawyers and managers etc. He mentions that the closing act was responsible for "going all out and take it all home" and that it was a agreed on that only blink were supposed to use pyro, but that GD decided right before the first show that they wanted to do pyro as well. The other example he uses is that GD refused to enter the stage before it was pitch dark outside, and also refused to cut their set, which made it difficult for blink to play before noise curfew, that Mark explained the problem to Billie, Billie said sorry and promised it wouldn't happen again, but did it anyway. 😅 Mark doesn't write it in a disrespectful way and he doesn't call them assholes or anything, he just states that GD was "out for blood" and that he sees it like GD didn't like to be reduced to an opening act.
