So I'm pretty casual as a shipper. Usually when I ship something, I enjoy both gen and shippy interpretations equally. I like Blorbo and Scrungus together, I like how they play off each other, and what I like about them is going to come through in both romantic and platonic interpretations. Yay for me, twice as much fun. I'm also predisposed to default to platonic interpretations in a lot of cases, because ace IRL.
So the fact that I *ship* ship Kronos and Methos, that I look at them and go "oh there is no way that is platonic" is noteworthy.
Usually when I'm doing that it's because the canon has palpable and often deliberate subtext (cf Mysterious Lotus Casebook).
But Kronos and Methos, I take one look at Kronos and I'm like "oh yeah, that's the crazy ex and there's weird noncon whumpy stuff mixed up with those millenia of mind games all right".
Completely unsurprising that the ship I *ship* ship has built in whump and isn't bosom friends or something nice like that.
Methos is just so whumpable! I course I ship him with the guy who wants to whump him >:)
