I thought Cary pointing out that he said 'phone' instead of 'call' was more leaning towards that he thought that Bishop was talking to Kalinda. British people say phone instead of call and maybe it was an adjustment of language to who he was talking to?

It's cool to see this being reviewed on AV club now and I liked the idea this episode put across a lot. Just wait til 'White Bear' which is the next episode. It's the best out of all 6 and I'm telling you that it's an obvious A+

In the Stray Observations section… It's Daniel Hardman, not David.
