[Sasuke seems to finally get over the complete mortification of having to talk about his hopes and dreams in front of everyone to chime in again:]

I took you to feed the cats in town, and you talked to me about how you used to do the same thing before. You liked it when I let you stay with my cat, Kurou, during the nights too - that's why you let me stay in the Velvet Room. When I started living there, you always tried to make sure I was eating properly. [Even if he ultimately didn't accept it.] And when I had doubts about my Arcana, or my hopes and dreams... you're the one who helped reassure me and try to think of something to want from life.

You lived on. The only reason we made it this far is because you did, and you used your time to support us.
