Bonnie hadn't expected to see Galinda there. They had some much weirdness between them, with Galinda's preemptive strike against Bonnie's friendship with Elphaba and then Bonnie acting like a total bitch to Galinda when they had been inflicted with sins, that they just tended to steer clear of each other with the understanding that neither one was going anywhere.
The younger witch had been good with that. But she hadn't expected to see the blonde there with her friends, trying to rescue her.
Bonnie vowed to put whatever it was that was going on between them, behind her the second Galinda spoke to her. "Let me help," Bonnie said, getting to her knees and crawling over to where Galinda was. "Give me your hands." Bonnie didn't have a lot of strength left, but whatever she had conserved, she intended to give Galinda.
