Two questions that stem from one:
1) I would think that his response could be canceled by something like He Calls It Thinking, but not something that targets character abilities (ala Meera Reed), is this correct?
2) If he were able to be canceled by something like HCIT(assuming it is possible), would it then fall into the same category as jumping Khal Drogo and Catelyn where you could trigger it again because it is coming from an out of play area(provided you have enough influence to pay for it again)?
Thanks for the help.
