Charge of the Valkyrie

A very lively discussion/debate in the Discord channel has been going on. The majority opinion is that in the instance of her attack sending the enemy character to the Infirmary she loses the option to displace herself one space adjacent to the Target since the Target no longer resides in the Hexadome. I am in the minority opinion thinking that her displacing movement represents her momentum of the Charge and that she would have the option of displacing herself adjacent to the space that had been her Target when the action was declared.
Also if she attacks a character that can displace, the majority opinion is that this deprives her of the charge displacement. I disagree. But I would interpret the situation that if her Target (such as 8Ball or Hexxer) succeeds in displacing two squares, she would only be allowed to displace once to a space that was adjacent to the space that the target occupied when the attack action was declared.

"Does a Mandatory double arrow Effect take precedence over the switches step ?" and Does the Target in Valkyries Charge refer to the Target space more than the actual character?"

Hoping for a ruling by -V- rather than further complex discussion

 

May a player using Charge of the Valkyrie choose to cause one less damage than would cause the Target to go into the Infirmary to keep the Target in the Hexadome for the "Displace adjacent to the Target?" This might come up say in the King of the Hill scenario if the Target with one hit point left is going to be trapped any way and sent to the Infirmary by one of Valkyrie's Allies.
