Summary
Tony Stark already knew raising a hyperactive 12-year old was complicated, but Peter has always had a way of beating his expectations. The kid seems convinced that Tony and his science teacher would get along, and Tony figures the least he could do is entertain it, so off they go to the next parent-teacher conference.
Ryland Grace turns out to not only be just as self-deprecating as Tony, but also a brilliant scientist in his own right - not to mention he’s great with the kid. The last thing Tony wants is to hear ‘I told you so’, but as he and Grace keep running into each other, the truth gets harder to deny. With Peter and his friends determined to ‘help’, it might even be more complicated than Tony first thought.
He had almost forgotten how it felt to experience a different kind of chemistry.

Summary
Following the events of “A Different Kind Of Chemistry”, Tony and Grace continue trying to test the hypothesis that they would be a good couple - and as is typical in Tony’s life, the answer comes in a pretty unconventional way. He’s made an effort not to rush into anything like he has so many times before, but he’s already given his heart away, and he’s not too sure he wants it back.
Luckily, Grace is here to make the decision a little more obvious - if it was ever a decision at all.

Summary
After a long week of back-to-back meetings, Tony wants nothing more than to go home and crash - but a call from Peter quickly changes his plans. Apparently the kid isn’t used to his favorite teacher being out sick, so Tony finds himself looking after Grace, who’s nursing some type of flu that somehow has him even more stubborn than usual. Tony is here more for Peter’s sake than anything, but he still catches himself thinking - which, according to Pepper, is a dangerous pass-time.
Just when he thought this day was complicated enough, his feelings have to throw another wrench into things. Because nothing can ever be simple, can it?

It wouldn’t be the first time he’s jumped in without a parachute, but at least now he knows someone is waiting to catch him.

Summary
It’s Peter’s 13th birthday, and Tony is more than ready to tease him about finally being a teenager. Before the party can get started, though, Peter turns out to have a confession that throws Tony for a loop - and, at the same time, somehow makes perfect sense. So, he figures it’s time for another of those tough conversations with Grace.
There’s a lot on the line, and he can’t help feeling a little anxious about it…but maybe he doesn’t have to worry at all.
