So by the end of the episode we see that although Impulse saved Flash and cured Neutron, the future is still apocolyptic which means that ultimately, Bart fails somewhere along the way and does not do as he was meant to and Neutron realises this. The only way this can be fixed is if another character is sent from the future by Neutron (or someonebody else, I guess) to stop Bart from failing at whatever he was meant to do. So It's possible another character will come from the future in a later episode?
