After Dr. Daniel Jackson's discovering of the seventh symbol on the Giza coverstone's cartouche. a team, led by Colonel Jack O'Neill, is set up; Porro is part of the team. Just before passing through the Stargate's wormhole, Porro reaches a religious medal and kisses it.
After an unusual noise and a big shaking, the team spread out. Trying to defend themselves against an unknown enemy, Porro sees Reilly knocked out and dragged away. Then he himself is knocked in the head by an object and falls.
- Porro seemed to be a believer, or at least a supersticious man. He kissed his medal he weared as a necklace before passing through the Stargate.
- Porro's rank is visible when he kisses his medal.
- Porro is credited as "Lieutenant" in the ending credits (the same for all O'Neill's team members), yet we can see "Airman First Class" insignas on his fatigues' sleeves.
- Porro's body is not seen after his knock-out. The Stargate books mention that Porro's body is deposited inside the water-filled pit, yet if we see closely the images, we can see sleeves on the T-shirt. On previous images, Porro had no T-shirt but an ammunition jacket without sleeve. Thus his status is MIA.
