She was so... super. If Bart was a cartoon, he would have floated straight off the ground and trailed along after Kara like Yogi Bear with a pie dangled in front of him, hearts in his eyes.
A goofy grin drifted across his face as Bart stared after Kara, trotting along behind her until they came up to the Tower and stopped.
And then it happened.
Kara leaned on him, still holding his hand.
When she did that, she made him feel strong, and heroic and like he could beat up any bad guy, climb any mountain-- like he would run as far as she asked him to and back just because she asked. His heart skipped a beat and he turned red, standing still and letting Kara lean on him, still holding her hand.
