Given that 'dark energy' is only a twinkle in the eye of some cosmologists,
any such exchange of influence would logically occur when gravity's attractive force exceeds dark energy's push. Dark energy is not however a necessary thing, only a mathematical fudge factor. Consider the integral of 2x. Is it not x squared + k where k is merely the constant of integration?
Yet had our 2x merely been the first derivative of x squared to begin with, then k would have to have the value of zero. In the same way dark energy is simply 'k' a constant that might have some influence if needed in the future. In other words it simply balances an equation; nothing more.

Alex I can't check any of this with the professor as he is on a lecture tour at present, but I think there is a danger of interpreting images without having strong observational evidence.
Consider this simple scenario; I crack an egg and place its contents into a bowl. Then I spill the egg onto the floor and throw the shell into the middle of the mess. Some time later you come along and seeing the mess, assume that I must have dropped the egg onto the floor, breaking it. That is what it looks like however you would be wrong. Later information might show that the shell was empty when it hit the floor, but for now you can only assume.
Abel 2029? accidental or natural?
Gravity....push or pull? (dinner break)
