I agree here with that’s the most likely.
However all options that have a reasonable possibility should not be ignored. I wanted to make sure we didn’t fall into that trap.
That being said I can think of a few reasons with the given assumptions
Geyde either poked at one or more of the scum
Geyde is considered a null kill.
Geyde was RNG’d.
Scum didn’t attack Geyde and were roleblocked by a blocking class.
Scum no killed and double lioned. (While I find this dumb it’s still possible)
