Just got done watching 45, and all I can say, is they definataly forgot about the Girty Lue and remembered about it when they were trying to come up with this episode. The way it went down was so anti-climactic, I swear it went something like this:
Crappy writer 1: Uhh, how should we kill Djibril?
Crappy writer 2: ...Hey what if we put him on the Girty Lue and blow it up?
Crappy writer 1: What's the Girty Lue?
Crappy writer 2: You remember, that one blue ship in the beggining?
That ship just went down way too easily, I guess that ship isn't equipped with Laminated Armor.
These so called writers should be kept away from all anime projects for the rest of their lives.
