Because you would think after nine seasons the Discovery hit would have thought of tackling zombie movie myths previously (before, say, trying to figure out if you can build a parachute from materials in your hotel room). But no, this is a first. We don’t know if there will be guest stars yet. We do know one of the myths being tested is attempting to figure out which weapon is really best for killing a horde of the undead (perhaps put an end to all those crossbow vs. machete debates).
