Speaking of which, Ballard and several heavily-armed security men are checking out the "party area" on the guy's roof when he catches sight of Alpha up on what looks like the helipad. It's hard not to wonder if he's just been waiting there indefinitely until the riddle was cracked, but if he's that tapped into the Dollhouse goings-on he probably was alerted by the mobilization of the security force. Anyway, Ballard calls for Boyd's team to join him, and when they all get up there, they see a still-nattily-dressed Alpha standing with one hand on a chair that contains the bondage doofus, who's wearing some explosives that look ironically like a life vest. Alpha starts to speechify about dressing well and whatever, but just when I start to think of him as the sort of Angelus-like Whedon villain whose blather-to-kill ratio is astronomical, he produces the trigger device for the bomb. Boyd desperately tries to tell Alpha that part of him knows this is wrong, but Alpha sneers, "There are many parts of me that know that this is wrong; none that care and six that just find it funny!" I can only speak for myself, but that seems about right proportionally. Alpha then goes serious again as he says that while Echo really loves these guys, they're all just using her -- not even all of her, just the parts they want. Boyd tries to say she doesn't remember, but Alpha knows that's not true, just as it isn't true with him. He forces the bondage doofus to confess that he called his time with Echo "a blast," and given what's about to happen I wonder if the guy who got hit by the car talked about how much he enjoyed "hitting that." Anyway, once Alpha grandly announces that everyone loves a pun, Ballard reads Alpha correctly and yells for everyone to take cover, and Alpha tosses the detonator into the air and runs. The action slows down as the bondage doofus closes his eyes, and I worried for a second that someone would come out of nowhere and heroically catch the detonator before it reached the floor, but no -- it hits the ground, BLOWING THE BONDAGE DOOFUS TO SMITHEREENS BEFORE OUR VERY EYES! Awesome! Once his guts have rained down over the surrounding area, Ballard and Boyd head back to the roof, but Alpha is gone. And while it doesn't seem strictly necessary to his plan for Boyd and Ballard to have shown up, it does add to the visceral sense of urgency they feel, which is always good for clouding an opponent's thinking. Besides, who doesn't love an audience?
