Having no doubt is bad news. It doesn't matter why. It might be what she needs as an assassin but not here. She seems to easily jump to wrong conclusions. Only doubt in yourself can make you rethink. What if she jumps to a conclusion that is fatal for someone?
It only needs one weakness... don't let her be your boogeyman. You don't stand a chance because you fight on the same level. Thor - he does the same. But she has no magic. She does not have one sixth of the universe in her possession.
I'd rather not go to them. How about making Fenrir jealous?
