Later, Broyles glower-walks through the hospital and comes up to Van Horn's wife, Patricia, who complains that "they won't tell me anything," and that's all Broyles needs to hear to go into badge-flashing threatening-stare time, and the duty nurse meekly acquiesces to Broyles' "request" for information, looking like she's worried she might get shot if she doesn't (which, admittedly, does look like a possibility).
Meanwhile, Newton of all people is striding through the hall to the emergency OR, where the doctor's confused because they're not getting any blood-pressure reading from the guy either. He's never going to find out, because Newton strolls in and tells him to step aside. When the doctor doesn't, Newton shoots him.
Hearing the shot (and a few more), Broyles gets his own gun and starts heading towards the sound of gunfire. Newton's rolling Van Horn's body out of the OR, effortlessly taking down security guards as he goes. Of course, when he's trying to hit any actor whose name is in the opening credits, Newton is a much worse shot, and he misses Broyles, who returns fire and manages to tag Newton, who grabs a hostage as a shield.
"I will kill her!" he warns, and Broyles orders him to drop his weapon. Instead, Newton shoots Van Horn in the face (Broyles is all "nooooo!" and I crabbily observe that each and every "noooo!" should be in slow-motion) then turns to go, shooting a cop and then jumping down a stairwell (that easy several-storey fall jump that we've seen shapeshifters do).
Broyles walks up to Van Horn and stares at him in horror. Oozing from the senator's non-human ripped-out eye socket is mercury "blood."
After the opening credits, we're at Massive Dynamic, and Peter is doing what he does best: undermining his dad. He can't believe Nina's OK with Walter taking over the company, and Nina says it was Bell's last wish, so it doesn't really matter what she thinks about it. "With a basement lab in Harvard, Walter was able to open a wormhole into another dimension that essentially shredded all the laws of science. I can't wait to see what he's capable of doing with a multibillion-dollar corporation," says Peter, and while Nina admits that Walter has made some "regrettable choices" in the past, his "brilliance is undeniable."
And then we go to Walter acting like your crazy drunk philosophy major uncle, babbling on in front of a room of completely terrified scientists about brain and consciousness, doing his hallucinogen-addled genius thing that we've seen a hundred times. It doesn't help that he refers to a scientist's black hair as red and yells that they're all "so limited," and then he starts to take off his clothes because it's getting hot in herre.
