Watching the Shroud explode right in front of her eyes, and knowing that her friend and lover was up there, sacrifice his lives to free the Krogans from their fate. Now the life that she always wanted with him would never happen, he wouldn't be able to retire to a beach and run experiment on seashells. She couldn't tear her eyes from the tower, she felt like she owe him this much. She felt tears rolling down her face and she found herself singing his song, replacing the 'I's with 'you' and 'him'. "Wait for me in heaven, Mordin Solus."
