Dove Cameron, a guest star for 5x02, shared her impressions on working with Robin and Simon.
And Simon…What can I even say about Simon. He’s goofy. He’s a goofball. He’s really funny. He was always running around set, being wild. He would always do things like; pick up a mini hammer, run over to me and tap my knuckles with it like they were marimbas. Or one time he hooked up a scary looking machine (Unplugged and antique, of course) to my finger tips and turned it on “Full Voltage” and we played Frankenstein. He’s a nickname guy, too. I always had a nickname. Both really lovely people that I was lucky to work with.
