Basically you and Sam are friends with the Autbots though Optimus, Ratchet, Ironhide, Sideswipe and Bumblebee have grown a little more attatched to you because you relate to them more and they can relax with you...but..today there a little pissed because humans held back specific information especially Optimus, so when you and Sam showed up Ironhide walked up to you two and said very softly "He's pissed" while Optimus transformed out of his truck form and started talking too one of the national security people
