Check an event overlap against 2 different actors of different classes at the same time?

there’s only one A, one B and one C. I don’t want different outcomes. Always the same.
To explain exactly what Im after:
There’s The main First person character (Let’s call him A)
And there’s an AI character (call her B)
There is a blueprint with just a collision box to be used as a region(C)- I will place this in Tight corridors only(and door ways)

AI(B) is following player, sometimes into a tight corridor. If I as the player want to turn around, i can’t because She’s blocking my way. Therefore
WHEN Player(A) and AI(B) are Overlapping with the region from C - Fire off event to make AI move away, otherwise (if not all these elements are TRUE) do nothing and keep following the player.
That’s why I need specifically A, B and C to be overlapping, but only one action(which is to get away from the player and move to a new location if shes blocking the player.
