Currently, Dismember uses the default Dismember animation when used on allies, which creates the weapon slashing sounds (this goes for Pudge and for Rubick!). Since the ally isn't really DISMEMBERED, the animation and especially the sounds make no sense.

Also, Pudge uses his default Dismember responses, too, GLOBALLY shouting whenever he swallows an ally. The Dismember responses should check for target alliance, and only trigger if the target is an enemy.

Also, the Eject sub-spell could make use of an animation/sound as well. Lifestealer's Eject had both, a sound effect and an eject animation.
