Before leaving the apartment, Quinn decided to inspect the whole place. All three of them looked around to see if they could gather any clues. For one, someone had to own the apartment in the first place.
Peter had stated that not a single person had visited the apartment during his time here, which meant that someone had purposely teleported them to this place and had prepared the room for them as well. On top of that, not one person had visited them during Peter's time in the tomb.
Either they were moved fairly quickly which didn't make any sense or something happened that had stopped them from visiting.
Whoever organised all of this, Quinn hoped that they would have left something, a reason, maybe an update of what was going on outside, but other than the container that Quinn was slumbering in, it looked like there was nothing else worth noting in the room.
