Three Little Words
The view atop the Presidium was incredible, magnificent, and breathtaking. Shepard didn't care that she was up here illegally with Garrus. She'd actually like to see C-Sec try to arrest a Spectre.
She had a feeling about why Garrus brought her up here. They were alone, looking out at a daunting yet incredible view of the Presidium. It was quite romantic. He brought her up here to inquire about their relationship. He'd given her time to think about where they stood. And now it was time for Shepard to make that decision.
So she told him three little words that are the most important words ever to say in a relationship.
"I love you, Garrus Vakarian".
And when he grabbed her and kissed her like he meant it, Shepard knew Garrus loved her too.
