okay so I thought this song really fit these three that have turned someone so I'm going to explain each of them to make more sense:

Scott: When asked if he's man enough to take to blame for his actions, he smiles, spilling his glass of blood. Scott isn't afraid to spill blood, nor does he feel any remorse about it. He doesn't take the blame fully however as he's seen victim-blaming pyro more than once. To Scott his actions are just the cycle of nature and nothing that should be seen as to be taken "blame" for, so he simply smiles.

Pyro: When asked if he's man enough to take the blame for what he's done pyro looks away in shame as if he's being scolded. He understands his actions and the depth of them as well as feeling guilt and shame. He killed someone dragging them into this life unwillingly, he stole his sire's meal. He can take the blame for his actions and feels remorse.

Shelby: When asked if she's woman enough to take the blame for what she did to avid she looks a bit angry at first, ("why are you asking me this") or resentful for what she was forced to but then moves to more a look of shame. She did not really want to turn avid and has some conflicted feelings about it. Shedding human blood, consensual or not is not something she wanted to do as a vampire. She accepts her actions taking the blame. She's hesitant to do so however, due to the fact avid was never supposed to be turned and Owen and Scott are mad at her for it. (mostly Owen) she feels guilt for "betraying" the vamily and turning Avid.

And the last frames are just images of them turning and how they died.
