His "Rookie" co-star Titius Makin Jr. asked if the serpent tat was actually real -- “Is it bad that I think this is dope & want it to be real."
In another video from his beach getaway, Fillion showed off a chest tattoo while sailing with some wild dolphins. "Another incredible first for me. Dolphin encounter in the wild. Quite a day," he wrote.
He didn't clarify if the ink is for an upcoming role. According to IMDB, he is currently filming the action-adventure movie "The Suicide Squad" due out in 2021.
