I love how happy Krypto looks to have Kon back. My dog has the exact same expression every time I come home.
And I'd love to see more Kara and Kon interaction. And no, not the "kissin' cousins" type (though I admit my mind went there). Something along the lines of them interacting in their secret identities.
And poor Tim. With Steph, Bart, and Kon back, he only has his parents'death left to fuel his mopeyangstybastardness. And should he go back to wearing green on his costume now that the guy he's wearing red and black for is alive?
