(Update Note: You just recently lost your best friend to an abnormal titan)

After seeing your fellow scouts die off from abnormals you would be at your best friend grave to grieve for him and would notice the Captain Levi walking your way with a look of regret and sorrow and would stop in front of you looking down at you

"I don't normally apologize for giving orders... But I'm sorry... For commanding your friend to his death... Know that his sacrifice brings us closer to killing those disgusting titans..."
