>>49052060you probably already know this, but you want to add a delay to the camera's ability to "chase". Do something like having two positions saved, kiki's current position and the previously saved position. Compare the two and if the two locations aren't the same, move the camera towards kiki's current position by some fraction like 1/10th of the distance every frame multiplied by some speed variable so you can further tweak things, this way the camera will move quickly when she's far and slow when near.
There's also smoothing stuff to make it less jittery but I forget how you do that, but it's easily googleable.
