Yes. At one point, we see an insert shot. Solo is supposed to be holding a Third Way identity card. Instead, we see a Thrush identity card, even though Thrush isn't part of this episode. In the climatic scene, it's not very clear why the rocket containing the thermal prism (and Sebastian) explodes. In the movie version, we see that as U.N.C.L.E. agents began destroying Sebastian's equipment, it apparently sent a destruct signal to the rocket and it blew up.
