[Discussion] So with Irene being a dragon slayer does that make erza one as well

[Sagebee]

Or is the same thing that happened to grey going to occur where Irene passes her dragon slayer powers to erza

 

[Bimbonium]

She might have latent dragon slaying abilities, iirc she didn't use magic on any dragon during the grand magic games.
Also, since people can become DS through lacrima "surgery" she stands a pretty good chance of becoming a DS, that's if what Eileen described as enchantment was not trying to implant her own lacrima into Erza, and since she's a dragon, Erza's already a DS.

 

[Styles]

Anything can happen just so Mashima can keep Erza in the spotlight and strongest.

So far nothing suggest Erza is one of DS. I doubt Belserion(A dragon) power had anything to do with enhancement.
