Well, hmm. I would say Nightingale and Greed probably are the easiest to point at and go "MALEVOLENCE!!" since those are the characters Mikleo has thus far had negative reactions around. With both, he's able to be around them and tolerate it, but it's extremely uncomfortable and he prefers to keep his distance.

So basically, if Tek is anything like that, Mikleo could talk with him as long as he isn't too close, but it might not be a long conversation in person unless Sorey is around to balance out the discomfort. Like a big fluffy anti-malevolence bubble.

does. that help at all. i have no idea how to explain, this canon is so vague
