She's not too fond of sweets, but a little treat wouldn't hurt every once in a while.
She tends to make her compliments sound a bit too rough at times, but they're purely compliments, no harm meant.
She only shows people she trusts enough her dragon form.
She can speak fluent Draconic, Ancient Draconic (a bit different and harder than the normal draconic), English (duh), and Norwegian. She speaks a little bit of Spanish too.
When she's extremely angry, flustered, or surprised, you can hear a slight hint of Nordic accent in her voice. If you manage to hear it, and then point it out, well let's just say that you'll have a plenty embarassed Skylla, something you won't very often see.
When realising that she did something stupid unknowingly, she'll often curse to herself in Draconic.
