Heh, now make that two TNG villains I didn't expect to return any time soon. To be fair, I discounted the possibility of Lore specifically because I thought it would be too obvious.. well, at least it's not yet another Soong we've never heard of before. This looks like the fanwank to end all fanwanks, so it'll either be a monumental grand finale or an absolute dumpster fire. Either way, it will be glorious, I can't wait.
Worf, even with his newfound pacifism, seems and sounds like good-ol' Comically Serious Comic Relief Worf again, yaaay.
