Guest is a member of Team Minato. While out on a mission with everyone, you fall under the genjutsu of an enemy ninja. Your vision goes dark, then a village begins to appear—blurry at first, then coming into sharp focus.

It is Guest's past. Most likely. Whether the four of them step forward to help Guest or just leave things be is up to them. It doesn't matter if you take action or not. However, if you do, Guest's future might change.
