That whistling coming from the kitchen in MCA Number Zero? That's not the teakettle. First because Xander doesn't have a teakettle, and second because it's the whistling of a happy man with happy pasta boiling away on the happy stove, who got to see
Version 1.0 of one of his favorite people today, and gets to have happy pasta for happy dinner with another of them tonight. In short, it's one of the best days to ever have the word "Parents" attached to it that Xander can ever remember experiencing. Largely because there have been no actual parents involved in it.
None of which explains why he's whistling Macho Man. Possibly it's the apron?
