So, if you recall when we were out by the train, we could choose from three different tools:
A monkey wrench (rusted shut)
A spike remover
Do you think this choice has any major impact on what will happen in episode 4 or 5 (since you will be wondering around in sewers according to the 'Around every corner' placeholder).
I went for the spike remover, I figured this unfamiliar looking tool would be the key to removing the train pin, but I was wrong and held on to it anyway.
