The shortest distance between two points is a straight line.
Note: Whilst this is an MSR overall, that's not its primary focus. This is dark and dirty... it features a very disillusioned Scully who is looking for reassurance elsewhere when she's not getting it from Mulder. No hearts and flowers here.
You know I like a side of angst, particularly when Mulder's being an ass in early season 6. This story documents an unconventional road trip with both Scully and Krycek feeling a little bitter over their circumstances.
