[ATLA] Did Aang and Katara kiss in the Cave of Two Lovers?

It goes dark for a second and then lights up, but I don't know if the lights turning on was a result of their kiss or if it interrupted it before it could happen.

The lights appearing was the result of all other lights going out. It was glow-in-the-dark. 

As for whether they kissed... only they would know for sure. But it *seems* like it may have been interrupted.
