Trying to Grab a Enemy by the head

[BaseReality]

Im trying to grab an enemy by the head in vr and pull them about a bit.
I want to recreate this system

animated via a three-dimensional blendspace of offsets based on player hand motion relative to the grab points. When the player releases the grappled enemy, it is thrown into a stagger animation matching the direction and speed of motion before release.

I have created the blendspace with the enemy leaning in all 4 directions & Im passing the world transforms of my motioncontroller to the enemy animation BP.
But Im unsure how I can make the blend space lean in the direction of my hand.
