She is very low iq, she got lucky in her first fight with Nunes then thought she was much better than she actually is.
Nunes is coming back either way and if Kayla wins in an impressive fashion Nunes will be motivated even more to show that she is still the GOAT against someone who only has 1 loss and someone she has never fought before.
That’s a tough one. If Kayla throws pena around I don’t know if nunes will want any of that.
