That's what fanfics are for, Time Laspe.
Shepard: Good morning ...
Ashley: Hey Skip *checks datapad*
Shepard: No coffee? Something wrong?
Ashley: No. It's okay. It's just that day again ... Shanxi. Surrender of General Williams. You know. Think I'll do it one last time.
Shepard: I heard the news already. Seems Hackett pulled some strings to set things right.
Ashley: Yeah, he did. Mind to raise a glass with me?
Shepard: Always.
Ashley: This is for you, dad. And you too, poppy. The family curse is no more.
Shepard: Amen.
Ashley: *snickers* You're not supposed to say "amen" after that one.
Shepard: Couldn't help myself. So ... curse lifted. Any plans now, "Admiral" Williams?
Ashley: I think I'll stay LC for a while. You know ... comes with some perks. Like commanding this ship. 'sides that, some people still think I don't deserve this rank. Jumping three ranks right after academy? That's unusual. Anderson pushed me hard and signed tons of paper just to get me as his CO since you weren't ... well ... available.
Shepard: Feels like another life. Right before the invasion. Before the war.
Ashley: Definitely.
Shepard: So Anderson made you to his CO, huh?
Ashley: That's what I said. Don't wanna sound cruel, but this entire mess, beginning with Eden Prime and the hunt for Saren, made me to what I am today. And cleansed my family's name.
Shepard: You earned it.
Ashley: I just wish I hadn't to earn it with the blood of billions.
Shepard: Yeah ...
Ashley: Well, that's all history, all done, yesterday's stuff, right? The only thing remaining is that rank and the knowledge "Williams" is not cursed anymore.
Shepard: Yep ... *empties glass* ... one question, Ash ...
Ashley: Shoot, Skipper.
Shepard: What did happen to your grandfather after he got drummed out of the army?
Ashley: Spent some years as a construction worker in remote colonies. Kinda lost track for a while, but ... well. I didn't say he died, right?
Shepard: No, you didn't.
Ashley: He formed a small militia group to defend one of those colonies in the Attican Traverse. Don't ask me for a name ... compared to our missions it wasn't much of a job, the Reapers even hadn't send more than one dreadnaught to seize the colony - and it just dropped some ground troups before returning to the armada.
Shepard: Did he survive?
Ashley: Why don't we ask him when he arrives on the Citadel? *smiles*
Shepard: You planned all this, right?
Ashley: One of those perks when you become CO of this ship. I always wondered why you never have asked your mom to visit us.
Shepard: Hmmm, think we had different things to do in those days ...
Ashley: Or you simply never had the guts to invite your mom. *grins*
Shepard: Very funny, Ash. When do we meet your grandfather?
Ashley: Think he should be in the "Apollo's" in an hour. You better get that stubble trimmed, Skip - he's no General anymore, but he still knows the drill. Don't wanna disappoint him, right?
Shepard: *scratches stubble* ... which one? Head or face? *laughs*
Ashley: Face, stupid. *smiles*
