This is a very chaotic issue, which is obviously intentional to reflect the breakdown of reality happening around the Flash Family. But that makes it challenging to read, because everything's happening at once and even the characters are discombobulated by it all.
Quick rundown: Hartley and TerrificTech figured out what's going on with speedsters causing reality to collapse, and Waller knows too after raiding the building to steal their data. Inspector Pilgrim's hanging out with Jai, and may or may not be his future self. Evan and co 'rescue' Barry from the Linear Bureau but place the Eobard-related Crown of Thawnes back on Barry to control him, and Wally's still in The Gallery but may leave now that he knows something's happening to Barry. As readers may remember, Wally was injured when Barry was possessed by the Crown and attacked him.
Like last issue, I sure hope it's the weirdness of reality collapsing that's got Barry "Good Gosh!" Allen swearing, because I find it quite jarring from him and am puzzled that none of the other characters have remarked on it. Barry noticed that Linda was acting unusually despite all the oddities, so it's not like everyone's completely oblivious to what's happening.
I can't say I'm loving this series thus far, as it's frenetic and depressing in parts and not a ton of fun to read. I guess we'll see what things are like after this arc is over and hopefully people start going back to normal again, and the Flash Family stops being awful to each other (there are exceptions; I really enjoyed Max telling Bart that he was proud of him when he thought they were going to die last issue). I'm also hoping we find out more about what's motivating the bad guys to get reality to collapse, because -- to paraphrase the Tick -- that's presumably where they keep all their stuff. But perhaps there's a higher method to their madness which will make sense when it's revealed, and Evan isn't really trying to doom the Rogues and Miss McCulloch to horrible deaths as everything crumbles around them. If so, the writer really needs to make that clear.
