Mulder, Skinner, Krycek related
Let's see, there's Batela's White Picket Fences where Mulder, Jeff Spender, Krycek, and Sharon Skinner were four of CSM's 10 children, making Mulder and Krycek Skinner's brothers-in-law. And Jo B's Life From the Ashes where Skinner and Krycek find out find out they had the same mother. (Both series are slash, which makes it interesting.) Are there any other stories where 2 or 3 of the guys find out they're related, brothers or brothers-in-law or cousins.
