Died: Season 3
Actor: Alec Utgoff
Poor Alexei. Just as we were beginning to like him, the Russian scientist got wiped out of the show. Kidnapped by Hopper and Joyce in Season 3, Alexei wormed his way right into our hearts, despite not even being able to speak English.
“Smirnoff” (as referred to by Hopper) was provoking indeed (but who wouldn’t be after getting the wrong Slurpee flavor?!), but it’s safe to say his childlike personality, infectious grin and obvious sense of humor will be missed!
