That was most definitely a scary experience, and as far as Cole saw it, they would not be able to deal with these things as they are right now, not until they had more people here to help. But that wouldn't be for a little while more, out of five million, depending on the amount that actually made it to the second floor if you considered just how much of a colossal hard mode the first floor had been; there was still some time before they got more aspirants in the glade.
A couple factors adding to it all is the fact that there was sure to be other glades, and beyond that since that brat Tiana was not here and she was the first to get to the third floor it meant she was in a different glade, and being the first means she would probably have a little bit of precedent.
