what is the creature going to be able to learn now that Safie has arrived? what kind of progress does he make?

Safie doesn't know the language of the cottagers, so she and the creature learn together (but separately :-D). The monster also learns to read and write after her arrival, and he is eventually able to understand and speak the language perfectly.

Easy question! Safie didn't understand the language of the cottagers. Eventually, they both learn the language together, as Safie is not bothered by the looks of the creature! So, later on, they both could read, write, understand and speak the language of the cottagers! It's just that simple! You're very welcome! anytime you want, just ask a question! I have a 98% chance of knowing the answer to everything!
