my idea for ash/alliance DLC.
you get a new message from allinace command asking to meet with you on the citadel.you go to the alliance embassy.inside waiting for you is admiral hackett and anderson (serving in whatever capacity counciler or admiral it works both ways) they tell you that a squad or division of alliance marines has gone awol and the alliance brass is afraid they might cause problems they want you to team up with there best alliance soldier and bring these rogues in or take them down.
they give you the coorodinates to meet with the alliance contact.when you get there the alliance contact turns out to be ash (or kai) cue romantic dialogue.after a heart warming hello and a lilttle bit of explaning (on both sides) you get to work.ash informs you that the alliance radicals are planning to destroy a turian colony.
this will remove the stigma as ash being seen a racist once and for all seeing as she is fighting to save a purley NON-HUMAN colony.kickass misison insues where ash and shepard procede to save the colony.all alliance radicals are killed (reluctantly of course).cue more romantic dialogue ash and shep heal old wounds and you are rewarded with a kiss on the check and a smile.parting of ways (for now

ash gets a medal turian and human relationships improve greatly all is well.....for now.you get another email from the alliance brass telling you to come back to the citadel embassy ASAP.when you return you find ash,hackett and anderson all with hauinted looks.
it turns out that the alliance retrived some of the dead bodies of the radicals and check the logs of the patrol ship the marines used and turned up some highly distrubing resualts......
THE MARINES WERE INDOCTRNATED!!!!!! they came across another dormant repaer on patrol and fell prey to it insidous mind control.there misson was almost 100% intended to ruin turian and human relationships further destabalizing the galaxy paveing the way for a much easier invasion.
BUM BUM BUMMMM!!!!!
lol this is my idead for pro alliance paragon ash DLC
