Calling a classic GoT forgetting what has been said in previous seasons. See Jon's birth name changing to be his brother's name between seasons
what? Why do you think that was forgetting something?
It was quite intentional. The half brother was dead he was named for him as a tribute.
And there have been like a dozen Aegon's in the books before Jon.
