tony and pepper will married in the future??

It is implied in "The Invincible Iron Man" comics por 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 tu look closely) "Virginia Potts-Stark". She's buried right siguiente to Tony, and siguiente 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 dicho that they are already married
