Amalie . . . he had never had much to do with his other sister. She wasn't as annoying as Naja was, but Egil spent his time out of the den, trying to teach himself fighting, far away from Amalie doing whatever Amalie did. Egil wasn't worried about saying goodbye to her either.
Really, the only lion he had any desire to say good bye to was his mom. And he felt he owed her that much, to at least say good bye and let her know where he was headed. She worried about them. So he waited outside of the den for his mom to return, so he could set out with a clean conscience.
