That was a point. If the station chose to mess with them again, and it was inevitable, John wasn't sure how to prepare. The wards could protect against that sort of thing. Possibly. Only time would tell and if they didn't work, maybe he could work out some way of creating the right spells and wards to defend against the chaotic nature of the station. It was like being in some sort of ever shifting personal hell.
"I'm sorry you had to go through all that" John replied. "Can't have been easy" he added. Things weren't entirely easy for him either, from the moment he arrived on the station, unsure as to how he got there. He had expected the Legends to come and find him but they never did. Were they even aware that he was missing? Maybe not.
"If the wards don't work, I'll try something else"
