Agent Wallin had been stranded not far from Stark Tower but managed to reprogram a SHIELD Capekiller mech he'd found and was leading a small group of SHIELD agents he'd freed. Wallin and his group had arrived to reinforce Hawkeye with some prototype Super Mandroids Chris had constructed a few weeks ago that'd survived the attack on the Helicarrier. Agent Barton this is Agent Chris Wallin, SHIELD Engineering Division. Sentinel sends his regards.
Chris opened fire on a couple invisible Skrulls tossing Clint a thermal lens for his aiming eye as the snarling creatures dropped dead.The cloakers show up on thermal sight. Oh, and I was told to bring spare arrows so lemme know when you need them.
