Worst actress in the show?

Agreed, Jadu was easily the weakest of the leads. While it's understandable due to them being young, the rest were all fine for child actors. Jadu was just bad. That's probably why she never got a lead role in an episode until the last two

I thought Merlin/Loppy wasn't particularly good either. Especially when trying to talk to the Dragon Lord. Sybil was fine for the most part but terrible whenever she had to do her crying scenes

Both actresses who played Ethel weren't that solid either

I'm gonna die of long hair!

she was awful. i think her and ruby cherrytree was cast as an attempt to right the ethnic quota but at least ruby was realistic with her lines. jadu was terrible
