Releasing the memories

Jonas has started to been given memory of pain not horrible ones but ones that leave you in pain for a while. For one night he was given the job to watch over Gabriel at night and put him back to sleep when he wakes up and that might when he woke up he accidentally gave him some of the lake memory and when he woke up again he gave him the last of it. The next day the Giver was in pain he had a painful memory and Jonas wanted to help so he let the Giver give him the memory and he finally experienced warfare. I think if the Giver was in pain too I would have helped him as well. I would die at the part where the horses are dying though just everyone in general dying. What will happen next to Jonas after the memory?
