I believe where the Sorcerer's Apprentice removed the potential for darkness from Emma and transferred it to Lily, it left a hole/void which is now able to be filled with anything should the person know how.

Now, we all know if anyone can do this, it's Rumple with 300+ years of magical knowledge. However, since Lily was close to Emma, it was kind of like a stabalising agent with the two of them being so close together and pretty much made them both whole again. However, since Lily lied to Emma about not having a family, she took this as a form of mis-trust.

My idea though. =l
