Alberto grins at the both of them, looking between both Luz and Luca as their conversation overlaps and they all feed off each other's energy, always enjoying their back and forth... But as always, Luz has some new tidbit of Human Knowledge for them that they've missed the memo on. However, also as per usual, Alberto doesn't like seeming out of the loop... He's gotten a lot better over this past years at taking his ignorance in stride, but it's never comfortable, so he decides to laugh it off. ...Just as ignorantly.

"Well, fuk-you," he tosses back, matching the pronunciation for the pun, teasingly but uncertainly. He pauses, then tags on, looking a little nervous. "Wait, was that mean? I'm joking. Ha..."

He falls easily under the influence of cool older guys in his life, and their friend Katsuki cusses a lot, but... Alberto doesn't wear it as well when he's tried. He's still learning the nuances of socializing, man, even after all this time. He's been dipping his toes into snarkier humor with varying degrees of success. His quick wit doesn't always serve him. But still, gaining some human-ing points, maybe? And at the very least, gaining some humble points, checking himself instead of just boldly charging through every interaction, keeping his blinders on. Asking questions, being vulnerable, being open. Humble points are probably worth more than human points, by now, after all.
