It looked like Larrick was using the transmitter in Jared's backpack to track them as far as that restaurant (the building in the snow). Elizabeth used the restaurant bathroom as a location for Jared to change clothes because the actual restaurant was closed for winter, which meant that there wouldn't be many people around. It's not clear how that transmitter got into Jared's backpack in the first place, maybe Larrick put it there previously, maybe Kate? After Jared changed into his new stuff, the old backpack with the transmitter was left in the trash. I don't understand how Larrick then tracked Jared to the train station just by using a paper map and making a few circles on it. Did he just drive to the nearest train station? And at the station in upstate New York, the janitor told him that Jared was picked up by a woman with a truck. Pray tell how Larrick is going to use that tiny bit of information to track Jared to the cabin?
Oleg gave Nina the money so that she could escape if Stan doesn't come through with Echo. Did he seem to be trying to silently tell her that the operation was not looking good and that she should book it now? Or just hold on to the money in case things take a turn for the worse?
Finally, the special paint sample absorbing shoes. Really? The Russians are going to give Fred some special shoes that are going to get enough of a sample of the radar absorbing paint just by his walking around near the project? Not buying it.
