''And also, even if she found out that Merlin has magic, that doesn't mean that she'll know that he's Emrys. Since she's only seen Emrys as old Merlin. So...yeah''

I'd love for Morgana to put two and two together, especially given that she just used an ageing spell herself, and realise that Merlin and Emrys are one and the same but I can't see it happening.

It seems more likely that Arthur or possibly Guinevere will be the next main character to learn about Merlin's magic.
