“I'm hoping you end up happily married to the man of your dreams and have a hoard of beautiful kids that'll keep you on your toes by turning your neighbours into various types of pond-life." He then shot her his signature grin. "But if it happens to be me, then I wouldn't say no."(Karl to Elena in The Witching Pen)”
“He took the pen and book from her and faltered.“Just write anything – anything trivial that won't matter if it comes to pass.”“Erm...” God, he was useless at this.Elena's hair turned blue.“Hey!”“What?”“I don't want blue hair! What the hell did you write that for?”“It seemed trivial.”“Blue hair – blue? That's trivial? What if I can't undo it?”Karl stared at her blankly. His throat went dry. He felt like a total dickhead, but writing really wasn't his strong point, so he went for humour instead and flashed her a grin.“I was going to write that all your clothes fall off, but figured you may have a problem with that. This was the second thing that came to mind.”(Karl and Elena)”
“Elena glanced up at him, taking in his words. “If you get rid of your fear? You know, I never look at you as someone who’s afraid.”“That’s because every time you look at me, I’m looking right back, and the only time I’m not afraid, is when I see you. And I do see you, Elena. I see everything you’ve been through, from so young – how you struggled through it; how you never let it destroy your hope and faith – and I’m afraid of nothing."(Karl and Elena)”
“You ever had a hickey? I want to give you a hickey.""Karl, we're not fourteen!""Don't bloody care. I was in love with you when I was fourteen -- your neck owes me a hickey."(Karl & Elena)”
“I love your independence, I love that you don't swoon, I love that you'll fight me with your last breath if you think I'm wrong, and if I ever have to catch you, I swear I'll make sure you're standing on your feet as quickly as you can manage it.”
“He pulled out a dagger from ... she wasn't sure where. Did he have that in his loin cloth? What else does he have in there? (Amy's thoughts, The Witching Pen)”
“Do you remember what we just did? Please tell me you remember what we just did."She briefly toyed with the idea of lying and saying no, just to see the look on his face, but she'd had enough of having her brain played with – it wouldn't be too sporting to do the same to him. "Yes, I remember, and don't you think for one minute that just because you had me on my back screaming I was 'yours'," she waved four fingers in quotation marks in front of his face, "that it gives you any kind of ownership over me, because it doesn't."He looked annoyed, then relieved, then he laughed. "Yeah, whatever, baby.”
