Making players chat with each other on the map

So I've gotten to the point in my adventure where I've added a second character, and there are times where I want her to exit the 'formation' and have the characters face each other.

It is weird to switch formation mode on and off and simply have her appear out of thin air, so I've been having an event with her picture show up and walk out of the 'group' using some conditional statements to set the player facing. Even if I did use formation mode, I would still need to set up a bunch of 'if's to find out where they are located. So I already know how to do this, because I've done it a few times now, but it's very time consuming.

Ahem.. so the question here is.. is there a simple way.. like some common script .. that would make: Character B, take one step out of the group and have both Character A and B face each other? Then have character B walk back into the group.. ?
