Although Sebastian isn't all words, he would also take action in seducing Valerie. He's always put so much into his words and has always counted on them. From flirting to advice, and even life lessons. He would do best through his words. When he lied to Valerie and damaged her trust in him, he tried doing and saying anything to get her back and get her to forgive him. She refused to hear him out and forgive him, since he tried to seduce her with his words from the beginning. But now, to win her back, he feels that all he ever gave was his words, and all he was left to use were his words. Since even his actions didn't work, all he can provide is his words. She's the one that has to choose whether to forgive him or not.
