Echo is an incarceration and interrogation facility in Dimension Two on the STARZ Original Program Counterpart.
Introduced at the end of Season 1, D1 Howard Silk is delivered to the facility on the orders of Ian Shaw. (See No Man's Land (Part 2) ).
In the run up to Season 2, promotional videos have featured Howard's interrogation at the hands of Yanek, but little is known about the Echo facility itself.
Yanek says his purpose is to extract information from D2 individuals that can then be used against their D1 Counterparts.
