Does the 'myth or legend' bit go with both clues or just the first one? I keep wanting to suggest Mr Teasy-Weasy for the second one but it doesn't seem to tie in with the 'myth or legend' bit.
Answer is always an individual, real or fictional.
No clue other than the cryptic for the "Blimey!..." clue.
Ravenclaw clue is mythical or legendary. Rowena Island, Canada?
