Maybe, but some things just don't add up. For example, why didn't Parker seem too surprised when she learned about MC's uncanny superpower? And why did she take a DNA sample from him secretly when she simply could've asked? It's almost like she knew. It's been hinted that MC could've manifested at some point prior to his night with Georgia, if so, assuming she's done the DNA stuff before, she might know before anyone, even before MC. And the person that sent the tiger must have known, 'cause there's no way that a guy attacked my mistake turns out to be the only dude with the potential to become the greatest super of all times. I'm not saying she sent him; I'm not even saying she knew for sure, I'm saying I don't rule it out, especially the knowing part. It makes some sense too if you consider Meri's story. Some powers may be unnoticeable, and MC was worried about his manifestation, but if he had manifested and his power had been breathing under water or being immune to radiation, he wouldn't have known, hence taking a DNA sample and having it tested was a good idea. Parker might have done it, but she didn't say anything, why?
Then there's the vaccine she's working on (allegedly). They had one, but the virus mutated. So, we're talking about some fast-evolving Kalavirus type of shit. If she creates a new vaccine, won't the virus just evolve again? I can only think they could try to inoculate everyone in a very short time, it's not a guarantee, though, but it might work... It's still a bad idea, 'cause if you try to force some dudes with cool powers to give them up, there's gonna be a global riot, and you're in some X-Men 3-like scenario. So, what's really going on there? Maybe they're not working on a vaccine at all.
Plus, cosider this: why can't the Sisters find out who sent the tiger? As said, must be someone who knows MC's power, and that means time travelling, world-class foresight, or the ability to tell one's powers. That should narrow down the search, but so far they came up with zilch, so it's logical to think that people with resources (like Parker) are covering their tracks... or that the Sisterhood's detective skills suck; I mean, I know they're not the Batman, but still...
