Just curious...

So, next up in the big bang plot is Outcast, the one where John's dad dies; this is the third time I'll have written about that happening (once for Wash Me Away, once in Coming Around Again, and then in this). This story also has my second time writing round Doppelganger (the first being Hide and Seek, which was Ronon/Lorne), and the second iteration of Rodney finding out about John and Cam's relationship (after That Which I Should Never Say, in the Return'verse).

None of which compares to the interval on Earth during the Return, which I've written I don't know how many times (three, maybe? Once in the Return'verse, once in Traveling the Line, with Lorne and Sheppard, and once in Life in 3D, with Lorne/Sheppard/Mitchell. Feels like more though). Not to mention the two different John-in-SG1 AU's.

So, I'm just wondering: other than the obvious, like two people getting together, what are the events, or the episodes, that you end up writing about most often?
