Wow.... I haven't gotten a chance to play the new one yet, but I just went to the official site. I knew Tira was f*cked up, but damn.... Also, I thought she waas straight, cuz in III she's looking for Nightmare thinking They could be lovers/kindred spirits.
Yep. Pretty sure that Nightmare/Inferno is actually yandere to Siegfried. I mean, just look at him and his moves. On top of that, Siegfried was essentially 'the one that got away', since he's the only host of the sword that hasn't died in its service, and took it very badly.
