While it’s pretty common knowledge that Thomas’ father is Daniel Vangarde, the rest of the robots’ parents often go unnoticed. Those with a keen eye will have seen that they are thanked on the back of Homework. Mamabang is revealed to be Therese Thoreux, and Guy-Man also thanks his parents, Didier & Anne-Marie de Homem-Christo. Paul is of course also mentioned, as is Helene Grand (Thomas’ girlfriend during the homework era).
Gosh darn it, French names are just so pretty.
