Anyone also catch:
* References to the Korvat colony, another oft-mentioned Klingon/Federation (who it belongs to changes hands with each telling) border planet?
* A joke reference to Dr. Soong's incarceration?
* Family Guy creator and star Seth MacFarlane as an engineer on Columbia?
* The freaky "mood-lighting" on the Columbia's bridge actually was part of a reference that the captain told Archer many episodes ago about re-routing EPS power through the bridge?
* The Columbia's almost TOS-like paint-job?
* The new Klingon vessel, perhaps an E-2 or an F-4, if we go by the SFC designations?
