The Clairvoyant's run in with GH325 has upped his crazy on Agents of SHIELD.

'Agents Of SHIELD' Finale To Answer 'The Big Questions,' What Can Fans Expect?

John Garrett (Bill Paxton) has spent the entire season seeking the miracle drug that helped resurrect Agent Coulson (Clark Gregg) following the Battle of New York and later saved Skye (Chloe Bennet), but now that he has it he seems to be taking it rather badly (see video below).

The HYDRA baddie is definitely up and walking, a relative miracle considering his organs were on the verge of total shutdown at the end of "Ragtag," but the wonder serum has knocked yet another screw loose in Garrett's already warped mind, making him sound like a rather stoned hippie.

"The drug didn't just strengthen my body, it gave me clarity of mind. It gave me a vision of the world that's waiting beneath the surface of this world. You don't think that's mad do you?" Garrett asks Rania (Ruth Negga) during "Beginning of the End," adding, "You know we're prehistoric creatures oozing out of the swamps, through the mist. Clawing our way onto land so we can finally stand. Or plant roots. Or fly...Now the truth is written on the back of my eyes."

Now that Garrett is "enlightened," his latest does of crazy will probably make him more dangerous than ever. Hopefully Coulson's crew will be able to take him out once and for all.

Marvel's Agents of SHIELD airs Tuesdays at 8 p.m. ET on ABC. Click the video below to see a preview of the finale.
