John Billingsley: Dr. Phlox

Quotes 

• Dr. Phlox : No wonder you erase memories. Your behavior is appalling!

• [the two aliens have been detected by Phlox] 

  Alien inhabiting Commander T'Pol : We come here only to study how physical species react to the unknown. You can help by telling us how you detected our presence. That happens in less than two percent of our missions.

  Dr. Phlox : Commander Tucker and Ensign Sato were sedated. They shouldn't have been able to stand and talk.

  Alien inhabiting Captain Archer : It's been so long since we had physical form. We weren't able to distinguish sleep from sedation.

  Alien inhabiting Commander T'Pol : We'll remember next time.
