Okay but imagine it turns out that Shepard is a very good singer. One night when she and Garrus and out with the crew, they jokingly challenge her to the karaoke machine. Everyone thinks it’s going to be a train wreck (Kasumi is there ready to record it). But when the music starts and Shepard starts to sing, the crew is stunned silent at how good her voice sounds.
The song she chooses is a cheesy love song that she makes sounds so lovely with her voice. Everyone at the table knows she’s singing to Garrus and thinks it’s the sweetest thing they’ve seen their Commander do.
If turians could blush, Garrus would look smitten red.
