Thanks for playing! Inside the lab there are some "forced fights." If you run away from those, they will pop up again within 2 steps because it's trying to force you to fight. If you beat that fight normally, it won't pop up again. Random encounters will pop up after a while after. It's all based on steps. So if you peek into a room and it doesn't have a forced fight, you can walk for a bit and walk out and back in and repeat the process and never encounter a fight. Once you've taken X amount of steps it will roll a percentage die and see if you have a random encounter.
