Saturday Night before THE Sunday Morning
We don't know the details, but we can be pretty sure from what the gospels do tell us that they were very apprehensive, even scared. They worried that they might be the next targets. Probably, however, apart from concerns that the disciples might try to steal the body the religious leaders were little worried about this band from Galilee. Fishermen, a tax collector, a zealot, and other less than influential people were not a concern. With Jesus dead, those who had followed Him would surely fade into obscurity.
Unless something earth shattering happened . . .
