Yor Forger Don't Get Drunk for 9 Months Challenge (Impossible)

Alright. Dad's a sly spy, mom's a powerful assassin, doggy's a seer, big(ger) sis's a telepath. What quirky hilarious power will this baby have that complement this nuclear-in-more-ways-than-one family?
I'll start: little baby boy with medium powers, is able to see the ghosts of everyone killed by mama and papa over the combined course of their careers, who chose to haunt them as a revenge. Fortunately, by this point in time, almost all of them have fully witnessed the weird wholesomeness that is the Forger family, and have kind of forgiven them, and even started rooting for them; and they try to help in their own way by playing with this adorable baby and teaching him whatever they know. Yor thinks his random reactions are cute, Loid's child psychology trivia is suddenly challenged, Bond cannot make head or tails of this little fella, and Anya is absolutely freaked out that two competing quartet bands were in her bedroom this entire time.
