Freddie Slater, played by Bobby Brazier, makes a big impression as he arrives in Walford – haggling at Billy's market stall and helping himself to a bap from Stacey's stall without paying.
Bobby later spots Freddie by the tube, where he is being reprimanded for jumping the barrier and takes pity on him by covering the fare.
