When you see multiple options, read through them and pick one. Then read onto the consequence of that option. If there are extension options (i.e. You pick [Option 2], read the [Option 2 consequence] and then there are [Option 2.1/2.2/2.3]), continue with them just like the normal options. They are extensions to the original option/consequence. Anything in normal text is meant for everybody. Everything in bold are your options or your option consequences.

1 – All That Remains

"How are you holding up, Shepard? This brings a sense of closure, doesn't it?" The speech was recognisably turian, but took Shepard by surprise, nonetheless. The voice, of course, belonged to that of Garrus Vakarian.
"After all the fighting, all the bloodshed… All we have left of the ones we've lost is a wall of names. This hardly does them justice." Shepard had been standing at the Normandy's memorial wall for several minutes before being joined by the turian. Garrus laughed descendingly.
"Count yourself lucky. Your name was on there too. Before you turned up in 'true Shepard fashion', of course. I heard that the Alliance communication guys were so shocked by your 'distress' call that they almost didn't make it to The Citadel."
[Option 1] "You didn't expect anything less, did you?" Shepard remarked, with a hint of a smirk. "Come on, let's go get a drink. I'll try not to poison you, I promise!"
[Option 2] "That's all well and good, Garrus, but some of us aren't so lucky," Shepard remarked, thick with grief. "I have Liara, you have Tali. Who exactly does Joker have, huh? With EDI gone, even the Normandy is slowing down. The galaxy is missing without her."
[Option 3] Shepard turned slowly towards Garrus. His eyes said it all, and the turian noticed. Longing. Disappointed. "After everything we've been through, are the jokes really necessary, Garrus? For what it's worth, at least let us remember our comrades without laughing over their graves."
[Option 1 Consequence] "Oh, I'll hold you to that!" Garrus remarked with a smirk. "Tali would be less than pleased" the turian joked.
[Option 2 Consequence] Garrus focused a longing gaze towards EDI's name on the memorial wall. "We all miss her, Shepard. Even the old prothean of ours," Garrus said with a light chuckle. "Don't beat yourself up over it, Shepard. You simply did what you had to do, and everybody knows that," the turian said with concern. "Come on, let's go get a drink. We could certainly do with one."
[Option 3 Consequence] "I'm sorry, Shepard," Garrus said with a great deal with sentiment. The turian meant what he had said, something Shepard had learnt over years of his company. "We could all do with a laugh from time to time, but maybe this wasn't one of them. Come on, let's get a drink. We could certainly use one." "Or two." Shepard replied, thick with regret.

The port observation room was a mess. Playing cards lay carelessly on the poker table, and half-drunken beverages were left on the bar. The previous night, a home-coming party had, of course, ensued. James and Steve had wanted to get the party going as soon as Shepard had returned, but were promptly shot down by Liara. Shepard needed rest, and he was going to get it. Here the venue was, a week later. With a sleek swish, the door slid open effortlessly.

"You know, you're not as good at poker as you are at sniping, Garrus." The previous night had not done the avian's wallet any good. Shepard's joke was met with a light chuckle as well as a knowing smirk.
"And I hadn't even begun drinking!" the turian remarked, almost with conviction.
"Not often that you're better at something than I am." Garrus' teasing was received in good spirits, as Shepard began clearing up the bar.
"I was going to pour you a drink", the human began, "but if you're gonna keep boasting like this-''
"Sorry to interrupt, Commander, but you have an urgent video transmission incoming at your private quarters." The slightly muffled comms buoy speech took Shepard by surprise. What could be so important? The Alliance was dealing with the political fallout of his decision to wipe out all synthetics, and the council had made sure to filter any calls from the public.
"Joker?" Shepard returned with tentative curiosity. "Are they leaving a name? What do they want?"
"They're purposely withholding their identity, Commander. All I can see is that the transmission appears to be coming from the Citadel. The Silversun Strip, to be exact."
"Near my apartment?" Shepard inquired with a hint of concern.
"The area's been repaired?" Garrus chipped in. With a collaboration of the galaxy's best engineers, the Citadel was almost fully repaired, mere months after it was used in conjunction with the Crucible to end the reaper threat. A drastically faster recovery than when the space-station had been attacked by Sovereign.
"Yes and yes." Joker replied. "Shepard, if the caller can hide their identity, they could hide their position. They want you to know where they are. Whoever they are, they've called eighteen times already. You better go see what's up."
