Why would they follow some random stranger when there’s urgency to get to the Falcon? Originally it’s because they’re spotted, and the random stranger kills a stormtrooper to help them.
You could keep that bit and remove “alert the local troops” from the Kylo scene, but with the stormtrooper identifying them the necklace thing would be pointless.
Lando killing stormtrooper needs to stay, shouldn’t get cut.
