It was never made obvious but se could have been. Maybe she wasn't jealous, just disappointed at the fact Chad no longer liked her.
In the episode 'Guess Who's coming to guest star' , she reminisces over her and Chad's relationship when they were seven. She berkata she was over it, however she had been talking about the kiss, and could have been referring to being over it. Not Chad.
Chad was most likely her first boyfriend. She could have felt as if he was somewhat hers and one lebih thing Sonny mencuri from her. Like: half of her dressing room, her spotlight, ect.
I notice sometimes when I watch the episodes of Channy's relationship, that in the background sometimes, tawni is making sad and 'gag' faces when they have an "aawwww!" scene.
Those are just the facts. I tried not to put my personal opinion in there, as some shippers do. But I am a definite Chawni Shipper and I cinta to think that Tawni was jealous.
Maybe. she could have been jealous of the attention sonny was getting atau the fact that Sonny gets everything she had. Examples: James, she kissed Hayden, spotlight, fans, and now Chad. But Tawni was over Chad since she did go out with lebih guys even though it was never berkata they dated it was assumed since they kissed when they were 7, but it could have been for their show, the goody gang.
