The Crisis appearance was actually spoiled a few months before the episode aired. Despite the paparazzi, Tom did his very best to say that the reports weren't true. Tom was in Vancouver, visiting a "friend" where Crisis just happened to be filming. Granted, he did say the friend was real but he tried to say he wasn't in Crisis, trying to keep the cameo a surprise for some fans. Like an idiot, I took his word for it, and I did believe him...until I saw Lux onscreen.
For once, I'm glad the Devil lied to me.
ETA:
And just in time, Part 1 of the new season is coming to Netflix August 21! 😈
