The simple version is:
In which Tate turns seventeen.
Gets kidnapped and meets his biological father.
Is revealed as Tony Stark's son and causes a media sensation.
When all he wants to do is date his superhero boyfriend.

Or, if you want Tate's version.

He misses his own birthday party, old family pays a visit.
He kicks a bitch and his boyfriend saves the day.
All in that order, while also accidentally causing a media sensation
(but the last one was mostly Callum's fault).

The life of Tate Doe Stark is not easy, but at least it ain't boring.
