The thing with the sewerage inspection robot was looooooong ago - way back in Chapter 1!!!
(And Tarik having been a newbie back then is quite the understatement, considering it was in fact his very first day at work!)
This page is full of shout outs to things that have happened throughout the history Cryptida, and I always think it's cool when a comic has been around long enough to be able to have a lot of references to past events.
And Tarik, you'll be fine. Probably...
And yes, Tarik will be fine... Depending on your definition of "fine" at least. Hehehe... ;-)
