Tony's impatience be damned, Wanda had to consult a map. She couldn't remember the last time she'd been out to Stark's Long Island campus, and it was better to waste a few seconds than to teleport them into a wall or out into the middle of the ocean. Before he could get too antsy, Wanda took Tony by the arm, and they blinked out of existence. They made a single stop so that Wanda could get her bearings, but they still arrived at their destination, outside the front doors, within moments.
She was surprised that Tony had her take him here at all, and as far as Wanda was concerned it was a tacit acceptance of her help. The pettish thoughts she'd had in the apartment, that this was his own fault, were long gone. He rarely seemed willing to let anyone help him clean up his messes, least of all Wanda with her habit of making things worse. This was a rare opportunity and since he was always handling her problems, she could try to return the favor.
Anyway, she reasoned with herself as it occurred to her how exposed she felt away from her secluded apartment, he'd have to get the other Tony back to her place. She was going to be the quickest easiest means to accomplish that. The sooner they located him, the sooner she could go back into hiding and hopefully the portal would behave itself for awhile.
