Searching for 2 M/K stories

The first one is an AU story.
It was from a third person POV.
That third person was a FBI agent, working with Mulder and Krycek (who was still a FBI agent) on a case.
The three of them were spying on some suspects.
That third person observed Mulder and Krycek seducing (or flirting) with each other.
He also saw them kissing by accident.


The second story is about Mulder were chasing Krycek (or the other way round). They stuck in a cave and there was snowing heavily.
That's all I can remember ^^;;;;;


Can anybody help me out here, please?
Thank You!!!!!

Regards,
Kate
