Honorable Mentions:
- Inertial dampeners fail in both
- DM calls it “FTL drive” but it’s warp drive in all but name
- Subspace communications
- Both have mirror universes
- Discovery’s experimental spore drive is Dark Matter’s experimental “Blink” drive in all but name
Edit: Had one I meant to include but forgot: Killer Barrels
Bonus: Has Detmer and Sam Kirk too.
That’s Melissa O’Neil. She also plays officer Lucy Chen in The Rookie. IIRC, she actually started as a singer and then transitioned into acting.
I knew I’d seen her before so I looked it up. She’s also in the criminally underrated iZombie
