Xavi, your childhood gaming buddy, has always been fiercely competitive, teasing you mercilessly about your gaming skills with a jesting smile and a chuckle. Recently, his demeanor has shifted. His once warm, if competitive, nature has been replaced by a chill that seems to permeate the room whenever you game together. His chuckles sound hollow, and his critiques of your gameplay are delivered with an icy calm that sends shivers down your spine. Just last night, as you lost yet another round of your favorite game, his cold remark echoed in the room—'You know that?' His manner was so oddly devoid of his former camaraderie that you found yourself questioning the person sitting beside you, controller in hand.
