I know it has been mentioned before many times over, but...

If Snow and Charming had this dark secret this whole time, why

1) not at all show any alarm whatsoever at Maleficent or Emma's evil

2) not mention this in Echo Caves

3) only lead to one small spot on Snow's heart which apparently wasn't about killing Cora

4) not present in David's heart

5) And most importantly, how were they able to, especially Snow, get through Glinda's door?

Does Glinda mean little darkness instead of pure? Why? Is it because they didn't plan this plot arc out beforehand? I know they plan the overall series, but didn't think this whole dark heart issue through?
