Hey Arnold! mistake picture

Girl Trouble / School Dance - S3-E18

Continuity mistake: Besides the fact that when Helga is sharpening her pencil, the desk arrangement changes, one of the students visible when she looks at Arnold is... Helga. This happens because the shot is taken from the episode "Helga's Love Potion."

Dinner for Four / Phoebe Skips - S4-E5

Rhonda: She asked you to do WHAT to my Caprini cardigan?
Lila: Snip the tags out?
[Helga grabs Lila].
Helga: Lila, what are you doing? You're not supposed to ask her!
Lila: I just didn't feel right about destroying Rhonda's personal property... without getting her permission first. It seemed, well, ever so wrong.
Helga: Yeah, well, guess what? You're ever so FIRED!

Answer: No, he did not. He is seen getting off the bus with a suitcase, so he must have not been home for a few days so there is no way he could have known.
