I don't know. Henry has the heart of the truest believer, and seems to be at ease around all of this fairy tale and Magic stuff going on. Besides, Zelena is his Aunt (by adoption), and therefore family. And we all know that Family does not give up on Family.

Another point. Henry has a good grasp of magic, and understands that Zelena may be the only way (other than the forgotten Malifecent) to get to Emma, so he would probably be up to a little risk to save his Mom.

And, after rewatching, we can now update the Severe Nurse to Nurse Rachet. that is now canon, rather than just head canon.
