To those who claim that Tali and Garrus are Shepard's "Real friends" for being squadmates in ME2. Well They can't do shit aout Shepard being in Jail while Ashley and Kaidan can flash their credentials and get Shepard out since you know, they have their own lives that don't revolve around Shepard and Cerberus.
They've got no Authority with the Alliance as they are a Turian and Quarian. Ashley and Kaidan on the other hand are the same rank, or outrank Shepard in the Alliance, and they are Admiral Anderson's right hand when Shepard is dad and when Shepard is with Cerberus.
Tali and Garrus wouldn't even be on Earth because they'd be tending to their own home world/Fleet in the face of the Reapers. Plus who wouldn't get suspicious of a Turian and Quarian on Earth?
But what was stated was who will get Shep out of jail. Besides, Archangel and Tali knew what happened with Shep. I'm pretty sure they would attempt to help Shepard.
Apparently everyone know what happened to Shep. Even Grunt. "Didn't they lock you up?" "yeah, but they have other problems now." If GRUNT knows Shep was locked up, they would too.
(Im sorry if this sounds like im trolling, because im not trying to) Because Garrus and Tali were preparing for the Repears! What were Ash or Kaiden doing? Jacksh*t, that's what. Not to mention the fact that Ash and Kaiden called Shepard a traitor on Horizon.
