(Just about Garrett and gabby tho...)

1) Both Garret and Gabby are able to make themselves partially invisible. To such and extent that if they broke a bone (or whatever else injury) hey could view the damage done themselves rather than having to get an x-ray.

2)Gabby has a photographic memory.

3) Garret has a memory similar to Hadwin (though not nearly as strong)

4) Garret also has a very high IQ. Though he's never had any formal education.He's still learning how to properly read and write because he's just now getting around to it. He is able to solve most any problem if he puts his mind to it. (And is also very good at fixing most anything, even though he can't properly read the instructions he goes by the pictures and usually takes whatever it is apart then puts it back together in order to fix it.)

5) The first name Garret ever wrote was not his own but in fact Noah (then Noel as a just in case he was the first to see it), he happily wrote his brother a letter to show off that he could. (Albeit a simple one...)

6) Gabby and Ethan spend a lot of time together, they like to sit out behind the house and have tea and a picnic. (It lets Gabby catch up on happenings as well as calms Ethan down from his worrying.)
