When unique characters from territory are brought into a side-battle, and that side-battle is later negated, are they counted as having 'entered battle' that turn and unable to enter again (such as through the other combatant playing a side-battle card or a banding card)?
Scenarios:
1. The character never entered battle, as there was technically no side battle.
2. The game tracks 'entering battle' itself, and the character counts as entering battle regardless.
3. Only CBI/CBN characters are counting as 'entered battle' (following the precedent regarding playing a card in general).
I would tend towards 2, but I'm honestly open to any interpretation because I can't find an applicable ruling (though I'd dislike 3 on the same principle that fuels my dislike for the rules on playing drawn cards being different based on whether they are CBI/CBN or not).
