Kendra works hard to hide her modern origins from nearly everyone in her new time period and struggles to explain the term serial killer to her 19th-century audience, given that Jack the Ripper wouldn’t be around for another 73 years. In a similar situation, would you be tempted to reveal your modern identity? Would you talk to anyone about pivotal historical events that you knew were upcoming? Would you feel any ethical responsibility to try and prevent disastrous events or to explain modern inventions (basic medical innovations, etc.) or would you feel that it was safer to let history play out organically?
