  • Before Critical Role's first appearance on Geek & Sundry, Liam and Laura fleshed out more of their characters' background over coffee in a café.

  • Matthew Colville, as a vampire, was also portrayed by Taliesin Jaffe in Critical Role One-Shot: Thursday by Night.[11]

  2. Matthew Colville shared details about this period and the circumstances in which he learned about Critical Role on his personal blog. The first date given there is wrong, as Matt would have met Liam before Critical Role launched, therefore in December 2014 not 2015, the same day he answered an AMA on Reddit.
  3. The e-mail Matthew Colville received and the reply he sent back are fully available on his personal blog.
  4. See also an interview Liam had with for Liam's point of view of the events. Note that in the interview Liam recalls the event happening "before [their] second game", tracing it back to early 2013, which contradicts the date given by Matt Colville.
