She pushes through ALL the memories of her father without missing a beat, which was one of the most tramatic events in her life that defined her personality (her alternate didn't experience it, and they're on two completely different sides of the spectrum), ignoring her past prejudices to help a friend in need.
Dan can get one himself, for recognizing his own Cerebus Syndrome, and making efforts to counteract it. As far as it can be told so far, quite successfully.
Also, Justin gets one here—Dan even says as much in the author commentary.
Melissa getting promoted from a madlimpet to a Girl With Guts, instead of Holding Out for a Hero standing against the... uh... dracobulldog who knocked out the local "superhero" right before her eyes and trying first to stare it down and then to make it disappear in a puff of logic.
The "Death Sentence" arc has one for Catalina and Rhoda: Catalina for making a Big Damn Heroesentrance to rescue Rhoda from a charging boar, then using her camera flash to scare it off; and Rhoda for managing to stop panicking, remember her own camera and join in on Catalina's plan rather than lie and wait for the all clear.
So. Somewhere in the universe there is something called a 'Deathless Army of Rage', and said army apparently had its sights set on Earth. Past tense, because this happened. Apparently, all that's needed to protect the world isn't magic or force, but a whiteboard and some Verbal Judo. It's the nonchalant hands-in-the-pants-pockets (whilst staring up a ...thing twice his size and half again as many limbs) that clinches it, though.
She gets another shortly after, when she meets with Ashley, Tom's ex. Ashley feels like an idiot, since Susan figured out in one day what it took her two months to discover. Susan delivers an inspiring and spot-on speech, assuring Ashley that Tom is the only one to blame for his manipulations, and that Ashley should never feel it's her own fault she was tricked. Even more awesome was that this was also in response to the fans, some of whom were suggesting that Ashely was an idiot to have been manipulated for two months.
Tedd's character development of awesome. In the beginning, he was a Chivalrous Pervert who was often the victim of Sarah's hammers. But after experiencing some very crude flirtations and finding out that some guys have been hitting on Grace the same way his first instinct is to find an immortal and make them replicate the magical effects of the hammers. And not just for Grace, but for all women.
It's very minor compared to, well, pretty much all of the other examples here, and very plausible in real life (Dan himself actually did this), but while playing against Tensaided in the Magickal Cards tournament, Sarah drew the fifth and last energy needed to summon O.P. Aludrakrala, but paused when she remembered Tensaided hadn't summoned anything when he had three energy himself. So she instead attempted to summon "Beefy Lycanthrope" instead, and Tensaided countered with Cancel Spell to stop the summon, just as Sarah planned.
