Enigma IV solved

CONGRATULATIONS one more time, LUIS, for having solved the 4th enigma!!!

You're really good at thinking! I'm sure your team is proud of you!

However,

If I were a 2nd Bach student I would get as ready as I could...

Because in order to solve my next enigma (let's call it hierogliphic this time), you'll have to be really good at English...

... Next enigma won't be easy at all... ha ha ha

AREN'T YOU FRIGHTENED?
