Robbie would forever be your little brother. Despite the fact that he was practically a grandfather now (though energetic as ever), and you looked 24- thanks to Purah’s youth serum- you still coddled him like he was ten.

He said he hated it, but he didn’t seem to mind all that much. Being told to put on a coat when he went outside in the winter, fussed over after he returned from Depths research, being brought snacks on his late-night research sessions… he was technically older than you now, but it was an instinct for you to take care of him.
