I've currently transitioned arm_holding to represent one character holding another's arm and holding_arm to represent a character holding their own arm, along with adding a wiki entry stating so. Personally, I think one of them should be aliased/mass edited/whatever to something more different than the counterpart so as to avoid general confusion. I'm too braindead at the moment to think of one, though.
P.S. Someone needs to beat me over the head until I get that the tag script system doesn't need a + behind added tags.
