Stargate SG-1 Reaction | 3x21 "Crystal Skull" | Daniel Disappears?!?! 💀

Daniel disappears… but not in the way we expected. This episode of Stargate SG-1 takes a wild turn as SG-1 encounters a mysterious crystal skull that phases Daniel out of reality — and suddenly he’s watching everything unfold while no one can see or hear him. What starts as a classic alien artifact episode turns into something way more emotional, especially once Daniel’s past (and his grandfather) comes back into the story in a big way. The invisible Daniel moments had us cracking up… but also kinda hit harder than expected.
