Did I hit the nail on the head? I did, didn't I? Aha! As expected of me, the great Slaine!
Feeling rather proud of himself after catching a glimpse of the embarrassed princess, Slaine mentally patted himself on the back on a job well done. Since even making her eat like a dog didn't seem to faze her - perhaps because she was one, of course - to get any real reaction from her was pleasant. His mood had instantly improved compared to what it was, so he deduced that teasing her was what he truly desired at this time. Nothing else would satisfy him.
"Is there something you want? Since lunch had just passed, dinner isn't until much later. I had already said I would be joining you and your family for that."
Slaine's grin turned into what appeared to be a genuine smile, though by now, Thea likely knew that wasn't actually the case. "Why, none other than to spend some quality time with my wife. Is that a crime nowadays?" he asked, taking a seat across from her and leaning it back. He rested his two feet on the table to emphasize just how nice and polite he actually felt like being right now. "Besides, you look absolutely bored! Look! You're reading! But...you know though, if you can't read at an advanced level, that would look pretty bad for a princess, wouldn't it? What would the public think!" all of this was said with a very genuine tone, but that just made the sarcasm more obvious. He had even thrown a little jab at her at the end. But, continuing his act, he threw up his pointer finger as if he had just discovered something.
"I have an idea! What if... your very generous and caring husband - me - shows you how to read? Maybe we can even make a bet out of it, if you're feeling competitive." he "offered". He likely wasn't actually being generous enough to let her choose what her answer was going to be.
At this point, he had gotten tired of the creepy-feeling smile he was wearing and decided to ditch it. He yawned audibly as he awaited the Princess' response.
