realistically? i'm not sure they're going to go there, but if they do, in true 911 fashion it's gotta be following a big emergency or incident during which one or both of them are forced to contend with their mortality — and at least one of them needs to have a Realisation™ before then, so that the GA doesn't think it came completely out of nowhere. they also need to give eddie a coming out arc, as well as resolve the clusterfuck they set up in s7, which will take anywhere from half a season to the full season — so imo if they're going there they could tie that into either the coming out arc or the buddie arc, depending on how much weight and time they want to give either of those. but if they do, i don't see how they can stretch it longer than s8 — we already feel like we're going in circles a little bit, because so much of the buildup and the foundation has already been done without actually getting to the finish line, and s8 is kind of like a. either commit or just don't do it situation already
