[PortalTron]

Just a random thought: One thing I noticed when I rewatched the episode is that when the Kamen Rider select screen comes up, there are only two question mark selects, despite there being three in both the commercial and Ganbarizing (I think).

EDIT: Also noticed that there are also greyed out versions of Ex-aid, Brave, and Snipe's portraits in the select screen, but nothing for Lazer, or any for Genmu (maybe the greyed out versions are Bugstar versions of the riders?), though it's probably nothing.

Double EDIT: There is a greyed out version of the portrait for Lazer.
