There were a couple scenes that were pretty out of order, like:

The vault hunters camping out in some empty bandit camp one night while on a mission and finding an old ass guitar, which they pass around while sitting around a fire. Axton and Gaige try to sing something, Salvador tries to tune it and sing something as well, and then Krieg ends up tuning it even more and singing some Johnny Cash

The mission in Thousand Cuts where they gotta get the explosives, and Krieg ends up hijacking a buzzard and uses it to keep the rest of the buzzards at bay

A series of events in Frostburn Canyon that serve as a more detailed version of the Cult Following missions, where some of the vault hunters actually have to go undercover and infiltrate the cult of the Firehawk

The Data Mining mission in the Arid Nexus, except the amount of slag in the area is too much for Krieg to handle and he has a mental breakdown and starts to mutate

Speaking of Data Mining, a series of scenes during it and after it’s over where Gaige downloads any info she can find on Krieg from the Hyperion database, and then spends a couple hours going through it in order to find out who he was and what happened to him

As well as a scene after Krieg recovers from the breakdown, where Maya is able to talk to and meet Inner Krieg for the first time, but she doesn’t know it

When Maya and Krieg start to get closer to each other and she ends up inspecting his necklace, and sees a memory from when he was in Hyperion custody that was imprinted onto it
