Uchū Sentai Kyuranger, Space 45: "Tsurugi's Life and Earth's Peril"

[Toku Prime]

So we just shoot this Planetium Bomb into a black hole like the last one?
No, Commander. The audience lives there.​

This week: lot of dramatic lighting on the bridge, they remembered Kotaro's little brother exists (still no sign of the mysterious uncle who was taking care of him though), oh hey did Tsurugi always have super speed?, the ninja wants to be a teacher, a really cool roll call, Champ doesn't seem that bothered about the death of his creator, and Lucky decides he feels like swanning around in his flashy coat again.

So what the hell was the entire point of the professor? What did his "reveal" back 10 episodes ago actually accomplish?

Also, did I fall asleep during the battle or did the rangers actually never physically fight him? I only remember there being guns and laser effects, no actual melee.
