Daryl & Codron's little moment in S206 at the campfire was a missed opportunity for Daryl to tell Codron that he lost a brother too

When Codron told Daryl how he had to end with Michel, makes me think it's very obvious that Daryl felt how it resembles the way he had to do the same with Merle, hence why he said "Yeah I can imagine", but doesn't tell him about it due to Daryl's nature and personality, and because it would eclipse the moment where he reveals Codron he wasn't the one who killed his brother.
