tony and pepper will married in the future??

It is implied in "The Invincible Iron Man" comics par Matt Fracttion and Salvador Larroca (in issue 500) that Tony and Pepper did marry. Unfortunately, the only proof we have of this is a barely legible tombstone that reads (if toi look closely) "Virginia Potts-Stark". She's buried right suivant to Tony, and suivant to Tony - their son, Howard II. And of course, their granddaughter is named "Ginny" (a very common nickname for Virginia) Stark and she has her grandmother's red hair to match. ;)

In the trilogy the very last of the trilogy it is a dit that they are already married
