What I just saw

I'm not sure why you mention you share the same ID. The Indy Pirate ID is a generic ID, in no way does having it mean you are part of a group or have to treat another bearer of the ID in a positive manner. Basically by saying that you are trying to strawman.

As to the real meat of your questions: Who says Anna didn't have her own agenda by shooting the Indians? You're a larger gang. Having you removed means she has less competition on her turf. Helping them shoot you might also been a survival choice. I don't consider it allying. You only consider it allying because you got killed.

I think the issue Joe has is that this wasn't a spur of the moment I'll help the RM shoot LN because it helps me or I'll help the RM because if I don't they will shoot me. This was, a Hey the RM are shooting the LN, lets go shoot the LN too!

Seeing as common sense isn't so common a more clear definition on the term ally would be great.

Thanks for the answer,i appreciate it and in some strange way you are right:D
