When approximately did Superman start hanging around with scientists like Dr. Klein? Was there a specific episode where he decides to turn to them for help with something, or did the relationship with Star Labs start off screen?

I think Dr Klein first appeared in season 3 in Chip off the old Clark, but I could be wrong

Close, Puffy. Some time back I downloaded all of the scripts and I just searched them. According to the script, Dr. *Peterson* Klein appears in "Don't Tug on Superman's Cape," two episodes earlier. This Dr. Klein was played by the same actor as Bernie; I'm not sure what first name was used in the actual DToSC episode, but I am guessing it is meant to be the same character.

Thanks! So, looking at the script for DToSC, it looks like Superman's relationship with Bernie and Star Labs started off screen, since they already have an ongoing vaccine-research thing going on.
