Nothing more needs to be said. We don't learn anything new about repercussions of the "incidents" being a main plot of the show, but instead we are given some explanations about few main characters' pasts. POSSIBLE SPOILER HERE!! It's a shame though that the creators didn't give more answers about what exactly was Jake doing in Afghanistan and Iraq. END OF SPOILER!!
Nonetheless it was (in my opinion of course) probably the best episode they served us so far. The ending is also very promising. Can't wait for the next one. Keep up the good work and keep us, viewers, more interested with each new episode!!
