re: #32 Dr Lizardo
Yeah, I could see a guest appearance by Riker, or Dr. Crusher or (hopefully!) Worf.

The Holodeck brought us Shakespeare, Isaac Newton, Albert Einstein, Stephen Hawking, Leonardo Da Vinci, Sigmund Freud, Mahatma Gandhi, Lord Byron, Socrates. There’s no reason it couldn’t bring us any and all deceased Enterprise crew.
