Abandon
It had been a month since she died. She was still all over the news. Of course she would. She was Commander Shepard. She saved the fucking galaxy. Only complete morons forget people who saved the galaxy.
Garrus had only been in C-Sec for about 2 months and he was already abandoning it once again. For good. He couldn't sit around and do nothing. The Council certainly wasn't taking any action about finding out who destroyed the Normandy. Garrus was leaving C-Sec, and the Citadel, tonight.
He had no real plan about where to go. His best bet was to catch a transport and let it take him somewhere far away from this hell-hole. He was done.
That evening, he packed what few belongings he owned and headed out. The transport he caught was going to all sorts of places. Perfect. Once he found a place that appealed to his interests, he'd get off there and start a new chapter.
