I do agree, Melissa, even if she does gripe about Abby at times (most of hers through do make sense), she does at least help out Abby. Christy I feel is going to end up costing her girls solos even more.
And as far as "arrogance/confidence" I am hoping Abby got the two mixed up. Some people do read the two as synonymous, even when not. Abby would definitely fit that frame.
