And based on Peridot's reaction, that yellow signal probably meant Yellow Diamond was sending help or something, so she's gonna think she has a way out, attack for a little while, then remember all the genuine moments she's had with the Crystal Gems and back down, solidifying her defection from Homeworld. That's my theory anyway. Or maybe she thinks YD's gonna help but she finds out YD wants to kill Peri for failing her mission and treason.
