Jeremiah Surd and Ezekiel Rage are both named after Major Prophets of the Old Testament. Since Dr. Zin is the third major villain, he should fit the Theme Naming.
Most likely due to her growing attraction to Hadji and to try to break out from being One of the Boys, Jessie rethought her look by exchanging the green for pink (even on her Quest World avatar), paying more attention to her hair and wearing make-up. It may have been prompted by Jonny making an off-handed comment like, "Jess doesn't need to be pretty, she's way too smart for that!" when he and Race were discussing the latter's taste in women and how Jessie took after her mother, both unaware that Jessie overheard them. Jessie knows that her intelligence is her true asset, but she's not immune to insecurity when comparing herself to older women (see "Eclipse" and "The Bangalore Falcon", arguably meeting Race's many ex-girlfriends didn't help) so she may be trying to compensate by "growing out" of her Tomboy phase as she sees it. If there had been a season three she would have toned down her attempt and started presenting herself the way she preferred to be; ironically, this more balanced look and attitude is what finally gets Jonny and Hadji's attention...
