im giving a new idea, not even sure if this is achievable, but if we will be able to do this, we will not only restore bob's branch but also we will be unlocking 1 of the most powerful magic here in the realm. how about if we try to look for ways to go back to time or to advance to the future (TIME TRAVEL). we can go back to time to see what happened to bob, we can ask Z what he remembered when bob's branch was hurt. but of course it is really different if all, the people trying to restore bob's branch will be able to see it. if we will be able to go back to time, we cant change anything. coz if we will manipulate the past, the present and future will be affected, so all we need to do in the past is gather information. then if we go to the future, there we will see what will be the results of our present actions, of course if we will be able to see that our action in the present will bring more devastating effect to bob, we can still prevent it or make theories on why such results came out, that way a better plan on how to restore bob's branch will be possible. but of course before that, we should try to find ways to travel in time, i think it is hard but it is possible, let us be a little optimistic here. in a realm of magic anything is possible. if we are trying to bring bob's branch back to life, why not try to travel in time to be able to make the restoration faster.the power of life and death is even more complex than time traveling i think
