I love what 4x05, and 3x05 for that matter, accomplish in terms of being unique episodes on the technical side. One being a no dialog episode & the other a faux 1 take. But they didn't pack that emotional punch that some other episodes in the series did.

Love your pick of MR. Robot 4x07 Proxy Authentication Required, but imma go with a different episode in the same series.

3x08 Don't Delete Me

There are two different law enforcement vs the security. The regular police got the greenish jackets. Tribal police got blue ones that kinda look like the security ones. But you can tell them apart because they got their bullet proof vest on the outside of their jackets.

You can see here, the police, including the one you think is security go to the right.
