I watched s2e8 and still have some questions. Can someone clarify all of these things? (v2)

\-Luke’s family took a note with the Extracted logo and wrote a fake Morse code - “Surrender your stuff and the next day we’ll give you even better stuff”. Isn’t it almost impossible to perfectly replicate typed font with handwriting? How would anybody fall for a handwritten note?

\-How did Roman’s family even find the fake advantage? Did Luke’s family place it Roman’s desk?

\\-Polly’s family took the fake note and now Roman’s family is yelling at Polly’s family. They’re going to be so mad when they realize they’re fighting over a waste of time. At least Luke’s family isn’t suspicious so far

\\-Did Luke’s family tell the other 3 families about the fake note? Or only Polly’s?
