Mother
Shepard couldn't even begin to imagine what Liara was going through now. The young asari just lost her mother. And Shepard was responsible for her death. Of course Liara knew Shepard had no choice, she was there. But watching Liara tell her mother to fight the indoctrination was saddening.
She hadn't spoken to Liara much at all, so it was awkward, deciding if she should check up on the girl to see if everything was going to be all right. What would she say? I'm sorry for your loss? That line had been used way too many times. Of course you're going to be sorry. Nobody wants to lose people, especially their own family members.
"Still thinking?" A familiar voice said.
Garrus. Of course it was him. Shepard shouldn't be surprised.
"Yeah. I don't know how to tell her I'm sorry" Shepard explained.
"I know you best Shepard. Just go in there and say whatever comes to mind. You do it every day on the battlefield" Garrus encouraged.
Shepard smiled "I'm glad I let you join the team. You always know what to say".
With that, Garrus watched Shepard walk into the med-bay to get access to the small storage room in the back where Liara stayed. You always know what to say. He let those words linger in his mind for a long time. They had that endearment tone to them again, proving the Commander cares about him. He liked it.
