Throwing out this hypothetical scenario for fun and I'm bored.
*loud talking in the war room*
Turian Admiral: I fear we shouldn't tell him, he's been rather impul-
*Shepard walks in*
Hackett: *nod* Commander.
*Every Admiral from every fleet briefly goes silent*
Salarian Admiral: We musn't risk a rescue operation, seventeen lives mean nothing while countless more are dying.
Hackett: You wouldn't say that if those were your men.
Salarian Admiral: I would, I'm thinking with cold hard facts.
Shepard: What's going on?
Salarian Admiral: Nothing that involves you, I'm afraid.
Kal'Reegar: He's helped us all, least we should do is respect enough to tell him.
Hackett: Commander, I'm afraid it isn't pretty.
Shepard: Tell me.
Hackett: While you went out playing hero, we spotted a Reaper orbiting Terra Nova. In fear of an imminent attack, we tried to contact the colony and found it's communications were cut off.
Turian Admiral: Spectre Williams suggested we'd send out a vessel with a lone operative to warn the colonies, though the chance of one vessel possibly surviving the voyage wasn't high.
Salarian Admiral: It's probability was 5.6-
Kal'reegar: He doesn't need to know that.
Hackett: We sent down a team, Williams was involved. A Spectre on hand boosted their morale.
Salarian Admiral: It was a trap.
Shepard: What?!
*the Admirals plays a recording of Ashley mirroring her distress call from Eden Prime, husks / brutes / cannibals are attacking the team*
Han'Gerrel: We cannot risk rescue, the Reapers don't know our position. Any movement can compromise our location and we don't have time to move the entire fleet quickly enough.
Shepard: Send in the Normandy.
Turian Admiral: Wouldn't do anything, they'd still track you. We have to remain in position.
Shepard: We can't just leave them down there!
Han'Gerrel: We have to.
Kal'reegar: Dammit Admiral, have some respect for the Commander.
Hackett: Commander, we'll do everything we can but I'm afraid we can't do anything right now.
Shepard: Do more, dammit!
Turian Admiral: I'm afraid it would come to this. Men.
*Turian soldiers come in with assault rifles drawn*
Hackett: Surely this is a little bit too much, Admiral?
Turian Admiral: He has to be restrained, take him to his quarters. Guard the door, make sure he doesn't do anything irrational.
Hackett: I refuse to let you do this to my soldier.
Turian Admiral: He's a war criminal who's just lucky he's useful, not any "soldier".
*Shepard is carried away, forcibly if you take the Renegade interrupt*
*cutscene of Shepard sitting in his temp quarters onboard the "shared" vessel*
Joker: Commander, are you okay?
Shepard: Do I sound like I'm okay?
Joker: I've got a plan to rescue Williams.
Shepard: What is it, Joker?
Joker: EDI made this channel secure, none of the Admirals or their man can hear any of this.
EDI: Down the hall across your chamber, there's an airlock.
Shepard: Good that does me, the entire ship is guarded by Alliance and Turian personel.
Joker: Seriously, Commander? That hasn't stopped you before.
Shepard: Hurry up and get the Normandy in place, Joker. I'll be right there.
Joker: Gotcha.
*Shepard opens his door and knocks out the Turian guards, he grabs a pistol and starts fighting through the hall as Turian and Alliance personel try to stop him. On the intercom, a voice is trying to contact the SSV Normandy and tells us to desist*
EDI: There should be a space suit nearby, locate it.
*Shepard dresses in a suit and goes into the airlock, a brief scene of the Admirals hearing the ruckus and realizing what's occuring happens and you see Shepard drift outside the spacecraft into the Normandy and the Normandy flying away. The Admirals immediately advise every ship that can to make a break for the relay*
*you drop down on the Hammerhead, you fight through Terra Nova's streets and see the entire colony is apparently huskified. You arrive to Ashley's locations to see her essentially repeating the "War Hero" story and defending civilians from the husks*
Ashley: You came for us?
Shepard: *smile, reaches his hand down* I never abandon my team.
Civilians: Thank heavens! / We're saved! / Yaaaay! / I'm going to post on the forums about this!
Ashley: *picks herself up* but... the fleet...
Shepard: They'll be fine.
Ashley: You placed them all at risk!
*Reaper moving in distance towards you*
Joker: Commander, we have to get out of here!
*You all leave back onboard the Normandy, you narrowly escape the Reapers and the civilians are thankful for their lives and the soldiers who were present are speechless. Ashley looks around worried as Joker tries to call the fleet*
Joker: There's no response.
EDI: I'm not picking up any life at the fleet's location.
Shepard: They've probably left, maybe we'll be able to follow the trail.
*The Normandy drifts where the ships were, wreckage is everywhere and bodies of dead soldiers are floating in space (think Dead Space's corpses)*
Ashley: Oh no...
Joker: We're getting a message, Commander.
Shepard: Play it.
Hackett: *furious* Commander, we need to talk.
END RESULT:
- Ashley is saved.
- Terra Nova survivors are saved.
- War Assets -5
- People aren't going to trust Shepard's judgement and might question his leadership, an Admiral or two could possibly die creating tensions between Shepard and that species.
- Ashley is absolutely furious with Shepard for deciding to save her causing a lot of drama in the friendship/relationship, though she eventually understands she/you can't change the past and you can "get over it".
- Bittersweet, you saved your love one at the cost of something else. No "happy ending" choice where you can have your cake and eat it too.
- No forced companion death.
