I was thinking the same thing. The I thought how funny it would be if their numbers were 156 and 239.
I guess it was too expensive to get Liz's dogs or Vesco's cat to tape a message which is why they didn't appear in the episode.
I appreciated the effort this must have taken and it was nice seeing the behind-the-scenes people get some on-air recognition. I agree the plot was nonsensical, but no more than any regular episode. I thought we were going to learn at the end that all the animated parts were Lizzie's dream b/c that's when she learned so many "truths" - like Red's illness. Sure, he collapsed in front of her, but in real life, it was just a bad bottle of wine, or he came down with the vapors.
It was funny when Ressler told Liz that she had to turn her mother b/c she's a wanted fugitive and Liz is an FBI agent. Yeah, b/c Liz hasn't broken any laws. Neither has Ressler. In fact, he's broken laws for her and she returned the favor when he went on his drive-about with this brother. But now, as FBI agents they have to follow all the rules. Got it.
