Who will be the betrayer in Vol.4?

Yet, after accepting the responsibility of helping to defend Canada, I thought that Mac would at least be a little ticked that his own government assigned him to go into the U.S. to get his friend....a very dangerous friend.

I agree there.

The "influencers" may have something to do with it, and if so that element would make sense, as well.

The oft-forgotten Influencer seemed to be Roxxon's thing, not Canada's.
Delphine makes a reference to 'Excellent, the Influencer is working perfectly'.
