Not at all! Being read is what they're up there for. :) I do have a couple of Dean/Gabriel there, but mostly what I've been playing with is variants within the dynamics of D/G/S/C. The big bang is officially S/G and C/D but can definitely be read as pre-OT4. Hope there's something you like there.

But yes, Sam/Lucifer has definitely got some interesting power dynamics - especially when you factor in the "Lucifer genuinely cares about Sam, but in his own very creepy way" element, which I think obstinatrix nailed here! :)
