Opening scene, Will and Declan see a distant building destroyed by demolition charges; the sight and sound are simultaneous. It is rare for TV or movies to depict the real world 5 second/mile time delay between sight and sound. In this case they should have seen the explosions at least 10 seconds before hearing the boom.
Henry mentions getting ejected from the Shin Bet computer system. Shin Bet, aka Shabak, is the Israel Security Agency (think FBI with a yarmulke).
