Will and Grace Oops!

I just watched the s5 e13 Fagmalion episode where G meets her new neighbor Julie (Arquette) the masseuse. Remember G thinks she made a pass at her so she asked K to book a massage with her and K came back and said nothing happened. FF to ep 16- same season - Women Children First episode where G hosts a girl’s night. Julie was invited. K comes in and talks to her and makes comments as if she’d never met her before. All the times I’ve rewatched WAG, I’ve never noticed such an obvious screw up - especially three episodes apart. Has anyone everv discovered others???
