"I told you I would!" He looks so HAPPY and EXCITED. The way Bruce and Tim are only focused on each other is even more adorable.
I also love Clark's face in the fourth panel, when he realizes that Bruce will be bringing work 'home' with him, and his look when he carrying Bruce up to see Tim even when Bruce has ruined the whole play. Clark is such a sweetheart, and the background fight is a beautiful display of teamwork.
