It just dawned on me that the main character in from the new game, Hogwarts Mystery remind me of someone we know from the books: I am thinking of Hestia Jones, who appear as a member of the Order of the Phoenix in the fifth book. She is, to the best of my knowledge, the only character presented to us in the books that I have any reason to believe fits into the story as the canonical counterpart of the younger sibling of Jacob. And this is why:

Player:
- Shown in promotional footage to be a female, though the players are allowed to choose.
- The same age as Tonks.
- Too young to have been a member of the original Order, would've been more than old enough by the fifth book.
- Deemed by Dumbledore to be brave, compassionate and resourceful.
- Open-minded and sociable.
- Comes from a wizarding household.
- Opposed to Voldemort (Angry when Jacob was accused of being a follower of the Dark Lord, and their boggart is Voldemort, so they're probably not a fan).
- Unafraid of speaking Voldemort's name.
- A skilled duelist.
- A good flyer.
- Particularly gifted in Charms.
- Goes above and beyond what is expected of students by solving the mystery of the fabled Cursed Vaults and saving Hogwarts, (presumably), and helps Snape spy on the suspected-of-being-evil Patricia Rakepick out of fear that she mean to do something that will threaten the school.

Hestia:
- Is a female.
- First seen standing more or less right next to Tonks, with both Hestia and Tonks being described as "young" without Harry noting one look older than the other.
- Not a member of the first Order, but member of the second one.
- Compassion - she was shocked to see the Dursleys treated Harry in the seventh book. Bravery and resourceful: She was allowed to join the second Order. Enough said.
- Hestia opposed Voldemort and his cause and appeared friendly with fellow Order members. She also was not so naive as to be fooled by the Ministry's lies.
- Comes from a wizarding household. (She laughs at a potato peeler in the Dursley kitchen).
- Actively opposing Voldemort as a member of the Order.
- The only one other than Remus, Sirius and Dumbledore known to speak the name.
- Stood guard at the Department of Mysteries in case Death Eaters were to try to break in.
- Volunteered to escort Harry as a member of the Advance Guard by broom, suggesting she is confident she can fly and duel simultaneously.
- Escorted the Durselys to a safehouse in the seventh book and probably is well versed in defensive charms to keep them safe and hidden. I had more reasons, but my mind is blanking for some reason. Maybe I'll come back to them later.
- The arrangement between Snape and the MC student would go a long way in convincing Dumbledore Hestia, if I am indeed right and the two are one and the same, is trustworthy and reliable enough to join the Order.

I really like to think that Hestia is Jacob's little sister and that her contributions to the whole Cursed Vaults affair during her education and her opposing views to the pure-blood supremacy of the Dark Lord and his followers convinced Dumbledore to reach out to Hestia and invite her into the Order. As seen with James, Lily, Frank, Alice, Snape, it is not uncommon for the Order to include recently graduated Hogwarts students, and if Hestia was the same age as Tonks, they both left school only about four years prior to Voldemort returning. And as the leader, no potential new member were likely to have joined the Order or even been made aware its existence without Dumbledore being consulted and giving it a green light.

What do you guys think?

 

Nah.

 

I think compassion is a very strong argument. Can't refute that. I didn't even look at the other stuff.
