I wouldn't call this blackmailing becausing the end result is still the same. I would call it having mercy. Quinn could have not bothered with giving him a way out and just gone with the second option. But he chose to leave that man's reputation in tact.

I don't like how Quinn thinks he is invincible. He could have very easily dodged that spell given how fast he can move, however, he chose to tank it. I hope he learns that he should be more prudent and never underestimate other people's magic.

A into B makes C. Done

The sins are Quinn's emotions amplified. Since he detests using a wand, Greed-Quinn may not seek out the Elder wand. But he may either be more greedy for more magical power or more greedy for relationships.

The last couple sentences shouldn't be possible, because it would mean that future-Quinn turned back the time of the last couple hours and placed present-Quinn just before he looked at RECON. So present-Quinn technically doesn't belong in this timeline.

Maybe this is how Quinn with get his Sin Vault issue solved.

Pretty sure Voldamort can make an educated guess as who the person is based on the timing of the first appearance at the village and the small clues everywhere.

Couldn't he just make one?

All this means is that Quin is not in perfect control of his magic. He hates how his wand can draw such a strong magical response.

The whole process is still faulty. Why channel the information into your own eye. Why not put a rune into an object and bypass your brain? This is a very dangerous method.

Why is no one talking about how someone can use the bathroom and not lock the door? Isn't this the first thing you do when you enter a bathroom to bathe?

If Quinn tells people he went to that shop. Then they may link Quinn with what happened inside that shop.

This also tells Dumbledore that it may have been Quinn who killed the trolls during Quinn's second year. Which may incurr that Quinn knew powerful dark magic at such a young age.

The wand weighing ceremony.

Death's Scythe?

Create a sword similar to Gryffindor's, that can change length/shape so that he can efficiently kill monsters in the earth vault. If he compliments his sword magic/skills with his body magic, we can all imagine how much damage he can cause without expending much magical energy.

Ron has 5 older brothers who are really smart and excel as one thing. Ron hasn't found his calling.

Why doesn't he use fire magic to burn everything away? He will never get caught in spider webs.

Maybe he can somehow use the blood in animals to locate their position.

We finally see some plot armour.
