After I destroyed all the monsters in the north area and headed back down, I noticed two things:

1) When I went to where Rhendon was originally, in the middle near the arsenal station, the charge tutorial would pop up. Infact, at the 2 o'clock and 6 o'clock positions of the arsenal stations, the tutorial would pop up again.

2) When I excited left, I was still able to shoot my gun, even though the exiting processes had started. I didn't try moving, but I think I could have.

3) Rhendon's after image was still there for a brief second before getting taken away as intended.
