Chechi's knockout wasn't that bad..... I mean it had its issues but the second half of the performance wasn't bad at all. Chechi's performance was better than the Kara vs CORII vs Kristine knockout and John should have stolen Chechi.
side note: I don't think Gwen was a good coach for her. If she had picked John, she would at least have had vocal notes to help her in the future.
