I think she's 21 and obviously got excited for Chris. Shes never had time on her own , having first crushes at school etc. The big brother house was her first experience of that freedom.Jojo is a dopamine chaser.
It’s all new and shiny and she reacts like a teenager, because she wasn’t allowed to be a teenager when she was a teenager…
Shes only 21 dated Kath a short time not like they were married.
