I could say that this is a depiction of Kerrigan struggling with the duality of her nature; her past life as a Terran (for all intents and purposes her human side) clashing and mixing with her powerful newfound Zergified self. I could say there is a deeper meaning to this. But that would be giving this far too much credit.
This is Infested Kerrigan, the Queen of Blades, with her human self. "With" with. This shouldn't be a thing. This should not exist. But it does, and I am so, so sorry.
You can blame
for this. This was his wish, and I drew it.
There you go, buddy. There is your Kerri x Kerri, molesting herself.
