I was expecting that, too.
I was expecting her to defeat Yon-Rogg and crew on the ship, get off with the Tesseract & the Skrulls, and then Talos stabs her in the back to give it to Ronan but she ends up stopping it. I thought he would briefly have a stone which is why he was desperate for one in Guardians. This would also radicalize him.
But I enjoyed what happened better.
