Tropes applying to her career:
- Those Two Actors: With Kristen Bell. Following a brief scene together on Hou$e of Lie$, they worked together on The Good Place, Bell had Howell-Baptiste in mind
for Veronica Mars's fourth season, and brought her on for Queenpins after her original co-star exited the project.
