Bare with me (perhaps bear is the better form -- as in bear wrestling which this reminds me of); I'm total pants at trying to manage replies.

Phew! There's a hazard to writing characters with identity and personal boundary issues.
In that example, showing the reaction of Person B to Person A's extreme interference is telling. An example would be of Missy reveling in the play of emotions across Twelve's face and his change in posture as she makes a naughty comment or three. It's still purely out of Missy's POV, yet through her catching sight of the sweat on his lip, dilation of his pupils, turn of his lip, etc, the reader can infer exactly what he's thinking without being told as much through his own thoughts.
IMO, it's fantastically harder to try and show both sides when all characters involved play things close to the vest or aren't particularly emotive. It becomes more inflection of whatever character you've chosen as the vehicle for the narrative.

omg, yes, I know! I actually think it's VERY difficult to pull off well, and have seen maybe one author do it (switching within a chapter). Otherwise, I have the EXACT reaction. :-/
I find it works best for comedy and satire where things can be saturated with metaphor and simile without coming off as schizophrenic. You get that extreme bird's eye view as a reader, but the chess pieces are still moved one at a time instead of tossed in a bingo ball roller. I think I may have seen it in one or two non-humorous works, and it reminded me of a relay race with how it was turned -- the baton was clearly and cleanly passed and quite a few paragraphs passed before it was handed off again.
It's a bit like watching a tennis match when it's constant back and forth, although with five balls in play and an automatic serving machine lobbing them out in random directions every twenty seconds. The only reaction is to head scratch then John McEnroe the racquet in frustration. :D
