The brothers Sotheby share an awkward glance over the grate. "Is that what they're scared about?" Gerald asks. Nathaniel shrugs, and turns away from the grate, prowling towards the cabin at the back. He draws his glaive, prepared for the violence he expects. Gerald follows suit, muttering to his allies, "Watch the door. Stay close. They might come running."

GS moves to M15. Use tactician to share intercept charge for the next 3 rounds. As I understand it, this movement happens before the charge. What I'm not sure I understand is whether or not it will allow AoOs. I know that the charge specifically denies an AoO to the target of the charge, but not to other enemies who may be afforded one.
In particular, I think that using the teamwork feat to move adjacent to the charge path but not into it would afford the user an AoO as the charger passes by.
