Harry attempted to obtain a useful object (such as Snape’s wand) when he knocked Snape over in Chapter 106. 75%
The ritual which promises to summon Death itself (Chapter 74) summons a Dementor. 80%
The lost counterspell to dismiss whatever is summoned by the ritual involving “a rope which has hanged a man and a sword which has slain a woman” (Chapter 74) is the True Patronus Charm. 80%
Harry’s mental development has been significantly influenced by his body’s descent from the Potter line. This includes genetic effects, heritable magical effects, and interactions between such effects and his environment, but excludes purely environmental effects of being raised in the Verres-Evans household. 70% (In other words, suppose the following counterfactual: Voldemort came to believe that the prophecy referred to a different wizarding infant child who had been living in a similar environment up to that point (canonically Neville also fits the prophecy), attacked that household in order to perform whatever mind-altering magic he actually performed on the infant Harry on the other infant child, and leaves all blood relatives who would otherwise care for the child dead / insane / otherwise unable to do so. Suppose further that Dumbledore asks Petunia to adopt this infant, so this hypothetical other child is also raised in the Verres-Evans household. My prediction is that there would be some significant difference between this hypothetical child’s mental development and Harry’s mental development.)
The procedure Voldemort describes that “destroyed all but a remnant of Harry Potter” (Chapter 105) involved a Horcrux. 75%
Quirrell was enhancing Sprout’s and Susan’s magic in the battle in Chapter 104. 70%
Snape is still capable of somehow intervening in Voldemort’s plot, despite the bodily control spell Voldemort used. 50%
Speculations:
Snape may be an Occlumens. In Chapter 27, Harry recalls that “the book said that a successful Legilimens was extremely rare, rarer than a perfect Occlumens, because almost no one had enough mental discipline.” Since Snape clearly has the discipline, the awareness of mind magics, the (at least outward) ability to pretend, and motivation to learn Occlumency (it would be extremely useful to someone in his position), he may well have become an Occlumens at some point.
Observations:
Quirrell is messing with Time. Recall Harry’s experiment with Time in Chapter 17, where he precommitted to an algorithm for recovering prime factors of a large number that relies on the stable-loop property of Time-Turners, but got the unexpected result of “DO NOT MESS WITH TIME” instead. His precommitment had failed to rule out the logical universe where he got “DO NOT MESS WITH TIME”.
Quirrell is clearly relying on the stable-loop property of Time-Turners when he says “Oh, we have time. There would be a great uproar if we were discovered here, guarded by an Inferius. You did not act like you had heard of such an uproar at your Quidditch match, before you arrived in this time and spoke to Snape as you did.” (Chapter 107) Leaning on this property to get what you want seems to be the definition of messing with Time, and also something we can expect Quirrell to be inclined towards based on his similarities with Harry.
Now suppose that Quirrell made the following precommitment in order to further lean on this property: “If my plot involving the boy known as Harry Potter succeeds in its objectives by 10:30 PM, I will then arrange for the note asking him to come to the forbidden corridor to be sent to him at such a time that he must use five spins of his Time-Turner. Otherwise, I will send no note to him.” This precommitment appears to guarantee his success if Harry shows up, and in particular appears to rule out universes where Harry shows up and defeats Quirrell. But it doesn’t rule out logical universes where Harry shows up and defeats Quirrell because it doesn’t rule out logical universes that can be described by “Harry shows up, defeats Quirrell, and then arranges to have such a note sent to his past self for the purposes of paradox avoidance.” So Quirrell just might wind up with a much nastier message not to mess with Time.
Adding to my previous prediction comment:

Particularly since Harry is just the sort of person who would send such a note. He knows not to mess with time!
Fortunately for Quirrell, I expect that he also knows this of Harry and so is not doing what you suggest in your last observation.
