So, is Bart considered to have disappeared until Shadowflick comes back to pilot him?

Also, concerning outnumbering bonuses. Are they counted based on the number of attackers ganging up on one foe with their attacks, or are they counted based on the number of combatants involved. I.e. if Winifred and Cassian attack the same guy, but a second butcher engages one of them in melee, is the 2 to 1 outnumbering bonus cancelled because there are now two enemies involved in the melee?
