Oh dear. This seems to have gotten out of hand. Mainly with Kenzo's face,I mean. If his face WASN'T like that,I would've said: " Jeez. With all these portals,we might as well dub this Aperture Science in Multiverse #19201516."
(If you split that multiverse number into twos/pairs and coordinate it with the alphabet,you can find a hidden message.) (It's a little comical response to all the portal and magic events.)
