Q: The movie 7aum Arivu, (meaning Seventh sense in english. This is the title in Telugu) is a 2011 Indian science fiction-martial arts film. It was originally made in Tamil and dubbed into Telugu, Hindi and Malayalam. The movie revolves about a genetic experiment conducted by Subha(female lead starred by Shruti Hassan). She knows that Chinese government is conducting an operation named operation Red. After some time, Subha and Aravind(protagonist starred by Suriya) learn that Subha's professor from the genetics department is assisting Dong Lee(antagonist starred by Johnny Tri Nguyen) in Operation Red. Subha and Aravind sneak into professor's apartment and know about the details of this operation. Here, Subha and Aravind search his house for details.

Q: In Spider-Man: Into the Spider-Verse, we learn that Kingpin wants to find a replacement for his wife Vanessa and son Richard by using their DNA in the machine that opens holes into other universes. (He uses a hair from a comb that gets put into the machine.)  But when Peter Parker as Spider-Man is fighting during the machine power up his head is pushed into the beam, which I assume was the reason why other spideys were pulled here because they share the same (close enough) DNA. Including Peni Parker (which could be a distant future relative in her universe, and even Spider-Ham (Peter Porker, which I'll accept as being close enough in his animal universe).  But as far as Gwen, Spider-Woman, how was she pulled into Mile's universe?  We learn that her Peter Parker was killed long before, so why did a portal/hole open up near her? When she would not share any DNA with Peter at all?  It can't just be the randomness we see from other universes, because we would have to assume there would be other (normal) people pulled in as well, not just spideys.  Maybe I missed something, but it just seems like they glossed over a valid reason.

A: How was Gwen pulled into Miles's universe?

Q: After his wife's death, John receives a small puppy named Daisy in order to cope and provide the company to not grieve alone.  At the end of the movie, after finishing his final act of retribution, John takes with him a stronger built pitbull puppy, and heads home.   Was this an intentional act of symbolism; with his first dog a representation of his fragile state after Helen's death, and the last dog a representation of a stronger, more willful John Wick?

A:
Was John's new dog at the end of the movie intentionally symbolic?
