Jo notices the changes. It's not like a tidal wave or some great big tsunami. She didn't wake up drowning in it, but she does see it. Senses it like beach water gliding over her toes as it crawls up the shore.
There something different between them. The dynamic is changing and is charged with something unfamiliar and scary.
It's not Jo and Lacey or Danny and Jo, but it's Danny and Lacey.
Sometimes he stares too long, or sits too close.
Sometimes she laughs too loud or smiles too big.
It's too different from what it used to be and Jo wonders if they are trying to make her feel excluded. They were suppose to be three best friends but something was growing and changing between Danny and Lacey, and it's evolving at such a strange pace that she can't tell if it's going to slow or moving too fast.
Maybe it was really just her, but why does it seem like Danny is constantly trying to touch Lacey? It's always presented as a game or some sort of teasing, but his hands seem to linger for no reason at all.
Why did it seem like Lacey was always looking for some reason to get his attention?
Why did he jump at the chance to give it to her?
Something was different. She didn't have to resort to her Nancy Drew persona to know things between the two were changing, but maybe her favorite character could use her skills for drawing out secrets to tell her exactly what had changed.
More importantly, why was it changing?
