As mazes feature highly here, it is interesting to note that you can solve any maze if you hold out one arm and touch the wall of the maze. It doesn't matter which arm, just do not switch arms. Do not stop touching the wall as you move forward and you will eventually find your way out. Depending on where you start, you may wind up walking the entirety of the maze, but you'll eventually get out.
During the sequence where Amahl Farouk is fighting David's dad (Charles Xavier), the chalkboard drawings David made in his mind of that battle from last season can be seen reflected in Farouk's glasses.
