Wolverine: Fine, but if he's stayin, he gets me as a babysitter.
Xavier: I'd prefer it if you'd get some rest.

Starting with this episode, all shows to premiere during season 5 featured a new opening credit sequence, taking bits of the old one, adding clips from previous seasons, and a slightly remixed theme song (with a heavier guitar score). Though, broadcasts in other countries used the old opening until the final 6 (see "Analysis" below).
Rogue is military pressing 65 tons in the gym, consistent with her strength in the comics.
The trucks have "Joe's Calamari" signs on the sides, another reference to executive producer Joseph Calamari.
Originally broadcasted as a one-hour special, back to back with its second part.
Star Trek: The Next Generation
The Phalanx itself is very similar to the Borg, an alien race from Star Trek. The Borg is a race of half biological, half mechanical organisms that roams through the galaxy, assimilating other races into their collective, always trying to reach their definition of "perfection".
