Sookie freaked out a little when she couldn't stop Melinda from making choking sounds or screaming. Sookie didn't know what Melinda had been talking about, but she guessed it must be that Melinda was a witch. Sookie had dealt with witches before, and honestly, she wasn't sure if she wanted to deal with one again.
Right now, though, she tried to get Melinda to stop choking. "Melinda, it's okay.... stop, breathe! Tell me how to help you!" She cried. She couldn't pull any thoughts from her head, and it was freaking her out a little.
