Hmm, so the depth of the ocean would point to The Little Mermaid. But I’ve already looked at The Little Mermaid. So how about being out of your depth?
Who gets out of their depth? There’s probably a few but I think Anna from Frozen ends up out of her depth trying to save Elsa while she still believes Hans loves her. Yeah ok she does manage to save Elsa in the end, but does technically ‘die’ before she does.
