So this was why people made a big deal about kissing. Bart totally got it now. Kissing was fun.
Tentatively, Bart reached one hand up to her cheek. He may have remembered people in movies kissing like that- but for once, Bart's head wasn't filled with pop culture, or fitting into the 21st century, or trying to appear normal. He wasn't thinking about the Speed Force, or his mother, or his grandparents, or Wally and Linda, or the Thawnes, or Max, or legacies, or disappointments, or bloodlines, or evil clones.
For a very rare moment, Bart's mind was still. And he touched Kara's face because it felt right, and natural-- and simply because he wanted to.
