The ITB suspended the set-aside on Pride. By the time Pride reactivates (which it must do due to the rules of interrupt), the Ignore condition is in effect. Since it now reactivating, Pride cannot target the hero for set-aside. Battle ends with everything but the Ignoring characters being set-aside from battle, because there is no SI back to the Bab:
You are considered to be losing by removal when an opponent’s special ability, or a game rule that has been triggered by an opponent’s special ability, would leave you with no character in battle when the special ability has completed.
ITB doesn't matter to cards that come after, by that point it is just like any other instant or ongoing ability played. Other ITB work as normal. Hope that helps.
