All right, this one here doesn't usually look like he doesn't understand anything in life. Tom here is usually smart, intelligent and is up to date with everything and ALWAYS finds a way to get his facts and information right. And that's a FACT. He's also too stubborn, like as stubborn as a MULE when he needs help in understanding what you say. The first time he heard you speak with your Scottish accent and language, he wasn't familiar with it at all and it was something he also saw as a threat. It most definitely wasn't Parseltongue, or regular English for that matter. What language were you speaking? What was with that accent? Were you insulting him in any way? if you were, you'd have a really heavy price to pay and of course, like always, he obviously thinks you're insulting him in some other language and jumps to conclusions

But he also has the ego complex of a freaking GOD, no joke. He isn't going to plead or beg you to repeat what you just said in front of everyone. He does have a reputation to maintain after all you know? He is the heir of Salazar Slytherin! What good will it look if he begs you for something? Instead he just glares at you with arms folded across his chest and tries to decipher what you're saying but somehow fails. But don't think he'll let you go just yet, he's got some words registered in his head already and when he looks them up from a book later, he finds out that you've been speaking Scottish. He mentally curses himself for not figuring that out earlier, he did have an essay to write for Professor Slughorn about potions originated from Scotland and how they could cure various illnesses

He also overheard you calling someone dear in Scottish when you were writing a letter to someone. When he found out after reading a book that you called them dear, he was infuriated with you and absolutely livid. Were you already in love with someone? No, you can't be, you belong to HIM and ONLY to him, no one else. No one else has the right to be called 'Dear' by you in your language, else he'll torture them and cut their ears off for daring to even hear that word from you. Don't you know you belong to him? Oh wait... he hadn't told you his feelings and confessed to you yet, oops.. but doesn't matter though, he's on his way to establish his dominance over you by claiming you to be his beloved so no one can steal you away and you'll finally belong to him

He knows where you'd be at the moment, during this time you'd usually be at the library and he stormed over to the library, dragged you by the hand to a secluded corner in the library and put a hand over your mouth to muffle your screaming as there was a dark glint in his eyes and he seethed "So, who the bloody hell was that? Who were you calling 'Dear' in Scottish? Oh, don't look so surprised sweetheart, I know it was Scottish. So, are you going to answer me or do I have to resort to other less than pleasant methods to extract that information from you?" he leaned in closer to you and whispered against your ear, making you shudder a little. The way you were reacting in such a situation truly delighted him, it was like he was gaining some sort of sadistic pleasure that only HE was being able to make you feel things like this. You didn't bother answering him and by now he was growing frustrated, he wasn't a patient man and his patience was running thin due to your defiance, he gently caught the bottom of your ear by his lips and slightly bit on it and you growled "Fine, I was writing a letter to my mother, now let me go you sick twisted psychopath!"

He grinned at you and whispered "There, now that wasn't so hard was it Mo Chridhe?'' and you turned red. He'd just called you my sweetheart in Scottish and you tried to say something but failed. He just smirked and hissed in your ear that you'll always be his and only his no matter what. Basically, he was asking you out and you had no option to refuse him. But surprisingly, he's very respectful about your culture and is very interested in learning about it too. Mainly because he also wants to impress you and gain the upper in your so called relationship so if you speak in Scottish with some other person and he's around, he'll understand easily. Even by languages there's no escaping from him
