First of all:big tight hug to Yug
Kairi is right,needs to let go of his past and hate! Only then he will find peace. Can't hold whole world weight on his shoulders,he's only human.
Not brothers but S1 is mini Yug,when something upsets him he's moody and angry and hard to convince. When Anya would be revealed as evil will see Yug was right all along;wants the best for the boys,not get married to divorce and go through same betrayal.
Yug defended Kairi cause her name is attached to his? Ok,go on with excuses,Kairi on! 
He really loved his uncle a lot,keeps having that death day flashback.
Imagination with small S1,so cute and emotional;no wonder he loves him the most and it hurts when S1 hates him.
Slowly taking out the pain he kept hidden all these years;with Kairi which is perfect,one day will tell her everything and that will be the peak of emotional connection between KaYu. The day he trusts her fully.
Kairi holding hot coal in her hand..she's bit crazy too. Another good idea:write L name and burn the paper.
Even if he couldn't do it in K presence he did it later,that's amazing,start of his healing process.
