I’ll make it up to you; if it’s the last thing I ever do
So I had a thought: Rapunzel is powered by/connected to the sun lily, and those weird rocks look like thorns. What do thorns do? They PROTECT flowers. What if the rocks, however hindering, aren’t “evil” at all, but trying to stay close to Rapunzel to protect her from an even greater threat? Maybe even Varian, if he continues down a darker path?
