Where did the CharlottexGertrude pairing come from?

from the land of awesome and win.

From the jet engine episode, at least in the anime.
Or maybe that's just sealing the deal after their cat and dog relationship in season 1.
Not sure about other episodes.

Mio x Minna...not a bad combo. And the pair in the middle is a lock.
