He’s got Linguini, a scrawny little 20s-something waiter. Stuart has a 15-year-old Jonathan Lipnicki who could definitely 1-v-1 Linguini plus two late-30s parents (even if Remy pilots him and even if the chef’s hat is off for max visibility, since 1) the family will know how this works and can try to get Remy out of the hair, and 2) there’ll be at least some latency in controlling him since it takes time to move the hair). So unless Remy is actively trying to kill Stuart, using a kitchen knife against his family with Linguini, he’s not going to get the upper hand. Remy has his family? Okay, have Snowbell get like a dozen cat friends and tell them it’s all you can eat.
