KI2T and KARR were both alone in the Airfield 73 main hangar while the other TKR AIs including Scout were out having fun somewhere the Trans Am and the Challenger both decided to look back on some of the events back in the day (the original series)

KI2T: KARR?

KARR: yes?

KI2T: i had this feeling i was never going to see my old body ever again after many years as an assistant AI

KARR: and i feared i wasn't going to have a third chance at life but i suppose life works in mysterious ways

KI2T: agreed *looks up an old photo of Michael, Bonnie, RC, April and of course Devon Miles* *sighs* they were some good times 

KARR: times when it was only one human and one AI against dealers, smugglers, murderers, kidnappers and even me

KI2T: yes and i sometimes got destroyed and even reprogrammed to kill Michael (Killer KITT episode)

KARR: tough times huh? well under Royaltons "wing" i felt like a slave and Garthe felt like what you and the other AIs felt "friendship" 

KI2T: agreed you and i are pretty old but we do tend to go on missions if the young ones need help or lending an extra hand anyways fancy going on the track for a bit?

KARR: *chuckles* even though you and i are almost 40 years old at this point we never get tired doing this!

the  Trans Am and the Challenger both went outside to the test track only to be attacked by the TKR AIs and Scout when Mike, Sean, Sarah, Takumi, Tyler and Linda began to throw water balloons at them 

KARR: STOP IT!! STOP IT RIGHT NOW!!! 

soon the team ran out of water balloons the Trans Am and the Challenger were freezing wet 

KI3T: consider that payback from that game of tag! 

KARR: why you little-!! 

KI2T: take it easy they were having fun

Linda: *laughs*

Mike and the team snickered 

Scout: *gently presses her tyre onto KI2T's* tag!! 

the TKR AIs including KARR and Scout drove away as KI2T began to chase them
