This creature reminds him too much of D'Vorah, and he's concerned it'll have her abilities too and fill him full of poison the same way she killed Hanzo back home.

For a brief moment he almost laughs, fitting for them to both go down the same way. Two grandmasters being bested by bugs.

But then he's back in reality and facing this creature. His hand tightens on the knife and the handle freezes, ice quickly descending down the blade to turn what was a small knife into an icicle studded sword. He swings the Kori blade down towards the centipede spirit, and he's not aiming to give any quarter. If he can decapitate it in one swing he will, but if he has to hack it to pieces... so be it.
