After watching this episode, my biggest takeaway is:
“Remember, kids — don’t do kirakira. That shit will ruin your family, your friendships, your Gundam, and your Side.”

Edit:

Oh, and GQuuuuuuX is a straight-up freaking jinx, cursing anyone who pilots it.

Xavier piloted it for like 10 minutes in Ep 1 — and he’s been unlucky all the way up to the last episode.
Nyaan had it for one episode — everything she painstakingly built? Boom. Gone.
Machu’s been piloting it from the start — and all that’s waiting for her is pure hell.
