I rewatched this scene and saw this little Douxie part. After all he went trough, after all he lost, he is still able to smile and cheer up. Even though I hate ROTT (mostly) and still don't get why Douxie had such a short and (exept for the body swap part) unspectacluar screentime, I still love him (and problably will never stop). He faced heartbreak, he lost Nari and Archie and STILL fights for his friends and for this world. He faces hell smiling, knowing that it could be over soon.
Somehow I get the "show must go on" (from Queen) vibes.
I'll face it with a grin
I'm never giving in
On with the show
Whatever happens, it is his burden - his show - to bear. He HAS to give it all. No matter what.
What a great written character. What a great wizard.
He still needs a hug though.
