How many of you were expecting the movie to end like that when Caleb first told Ava his plans for escape? I had a feeling Nathan was going to find out somehow so Caleb would have a change of them but I wasn't expecting him to get fucked over.

 I do love that the movie ends in a more realistic approach. When you see the footage for the other androids they all were freaking out, but not Ava. She simply acknowledge where she was at and handled it and when Caleb came she used him. She basically mind fucked him when she told him Nathan tells lies and not to trust him. Fooling Nathan would be hard but for Caleb which is a guy that knows nothing about her would be easy. All she had to do was fool him into thinking he was in control or that she was fully with him. Then once her chance came she didn't need Caleb anymore and she went her way. You can tell she no real attachment for Caleb when she walked by Caleb and didn't look at him and she didn't look back when she left the entrance. She just kept on walking to the helicopter as if she's not leaving anything behind.
