Alberto is all ears as Luz describes the plot of the series, always appreciating her enthusiasm and thorough detail in all her explanations... They really did pick the best Humaning Guide ever. He smiles as they listen on, smile just widening when Luca refers to them as best friends. Nothing he doesn't know. He just likes hearing it. And he could tell from their vague online search that the characters they chose to cosplay were definitely a pair of some kind, but he didn't really look much into the nature of their relationship. So he's just as eager as Luca to hear if they hit the nail on the head by sheer coincidence!
