Ya, they ran out of time and were unable to go over the teachers motive, also the manga had a few chapters left that weren't written yet so about half way through this episode they started guessing the rest. The last 2 episodes feel rushed as a result.

Part A had a nice reversal but that's about it. The spider thread "motive" is pretentious from out of nowhere... The timeskip with no explanation as to how he survived or what happened exactly was also quite lame (one would expect his time travel ability to set in..). All in all another episode not carried by the presentation.
