Breaking Bad‘s Giancarlo Esposito will make his debut on Once Upon a Time this Sunday – read on to get a preview of his character, The Magic Mirror!

Lana Parilla (Evil Queen) tells TV Line:

The Magic Mirror is [the Evil Queen’s] inner voice. It’s almost like truth… like her subconscious… like the part of the brain that doesn’t lie. [She uses it not only to] see what’s going on in the Enchanted Forest, to see what Snow White’s doing and where she is, but also to seek answers and some truth.

We wonder what Esposito’s real-world counterpart will be like. A taylor maybe?
