wait so to clarify the person who you're talking to is claiming to be a ti, are they claiming they checked sunny as plague or that swurtle gave them info about sunny herself?
because i thought she might be lying about chef - on account of potentially misremembering how chef works and forgetting chef doesn't get told waiter alignments
considering swurtle has, if sunny is plague, completely thrown them to the wolves metaphorically speaking, i doubt she'll want to reveal the 3rd waiter
