When Regina took the serum she splitted in 2 different versions of herself (I mean, both played by Lana Parilla), which makes sense to me

But when this wierdo guy Jekyll took the serum, he s plitted in 2 completely different persons. Hyde and himself

Why does Hyde look different from Jekyll, while Regina and the Serum EQ look the same? Do you think this will be explained?
