Taking Action
Home seemed emptier without a mother around. Garrus couldn't believe already 2 weeks had passed since her death. At least she was in a better place. Her disease had gone on long enough and had caused her too much suffering.
After his mother's death, Garrus started to get a grip on things. It was time for him take action. He needed to explain to his father and sister where he'd been for the last 2 years. He owed them that explanation. They also needed to know the truth about the Reapers. He didn't know how much longer they had until their arrival.
If he couldn't save his mother, he could at least was try to save his species. And in order to that, Garrus needed to gather help.
