What is the context of "רגע" in the following?
שלום!

I am watching Peter Pan in Hebrew and I don't quite understand the word "רגע" in this context:
Peter, "Kamo van, aval la/ le olam-lo chashav... (I can't make sense of the rest. They talk too fast)... Rega!"

After he says that he sprinkels the dust over them... (if it helps, Wendy wanted to know how they were going to get to Neverland)

I'm sorry... It's a hard question because it doesn't make sense but I would really appreciate any help :)

Answer

In this case רגע is like "wait a second".
Peter said: "kamuvan, aval le'olam lo hashavti al ze be'avar... rega! yesh!"
Translation: "Of course, but I never thought about that in the past... wait! I got it!"
Peter said "yesh" (have) in a way of "I have an idea (how to make you fly)!".
