I noticed an interesting section of the REG:
"Captured characters may only be targeted as captured characters, or “captured” versions of their identifiers, brigades or card type prior to being rescued. However, they may be seen or counted by abilities or identifiers that look for their identifiers and/or brigades."
Since captured characters are meek, would having a captured character in your LoB satisfy a requirement such as "if you control a meek character"? I don't know of any current application of this ruling but I can imagine such a phrase appearing on a card someday.
How about situations beyond meekness? For example, does having a captured character who is a priest in your LoB satisfy King Abijam's requirement?
How about brigades? Is Affliction of Job X=7 if an opponent's only card in territory is a captured Foreign Wives?
None of these are things I would have thought to be true but that's what I understand the bolded section of the quote to mean.
