Show's inconsistency with Aegon and Sunfyre

S1: Aegon has mastery over sunfyre (Dragonkeeper tells this to Jace)

S2: Aegon can't speak high valyrian and is supposed to be a pathetic dragonrider

S3: Speaking high valyrian to wake sunfyre?

The show writers themselves don't know what direction they should take regarding the two. It's pathetic atp.
