Sad to say, I have hit my endpoint with Janine, I think. Charlie just doesn't seem to know the character anymore. You could feel it in that Christmas episode. She has moved on, and likely never would have returned if not for the pandemic.
The last episode was fine, very strong even, up to the point she went back to the house. Janine would have just left Walford when Linda gave her the out. They wanted to overload the whole Janine/Scarlett dynamic one last time, which didn't even work, because the girl who plays Scarlett can't act. Ricky lashing out at her also felt unearned because we have barely seen their relationship in his return.
The whole Mick/Janine story really hollowed her out, and they also made her relationship with Frank into a bad joke, which is something it's going to take me a long time to forgive as a fan.
