This was my second read of this fic and I'll admit I enjoyed it a lot more the second time around. The first time I got stuck and frustrated a bit with the things others have mentioned already (Mulder is sooooo good at everything and Scully is just swooning). This time? I think I just enjoyed the writing. And the MSR of course. I also think I somehow didn't catch the early season nature of it the first time around, and due to that the whole fic felt sort of off.
This time my biggest frustrations were typos, wording errors, and unreliable use of tenses, which were throughout all three parts but weren't enough to seriously detract from enjoying it.

Also, hot sex in parts 1 and 3 aside, I too liked the second part best. That was great having the action unfolding both in the courtroom and in memory, and I really enjoyed the way the courtroom action went. Lots of slow tedious lawyerly interruptions 😊
