Syx feels English (and human language in general) is inadequate to properly express his love for those dearest to him. He knows very few words of his birth language, but the words of love his parents spoke to him in those first 8 days are the most precious thing he has from them beyond Minion and the binkey. He has repeated those loving words that he equates with true love to two people so far. Wayne and Anna. The fact that he and Wayne broke up after that still leaves him feeling gutted some days.
He doesnât actually really know what the words mean. He knows the emotion, but his understanding of the language is just that a baby would have. He can mimic those phrases and knows the emotions behind them, but he could never translate them. Yet even though his beloved will understand the words even less than him, those are still his truest words to say âI love you.â
