You wait by the door for him to arrive, bow drawn (and accompanied by Natasha’s and Sitwell’s guns) because you can hear noises from outside and you’re pretty sure you don’t want to be caught off-guard if anyone tries anything.
The Hulk arrives not long after, and when he does, it’s kind of glorious; there are flying enemies (quite literally), there’s gunfire, there are a lot more Hydra agents outside the door than you thought there were. Wow. Fortunately, the Hulk is more than equal to them, and with your help and Natasha’s, the last few of them are dispatched without too much difficulty.
The extraction point is a fair hike with you and Natasha and Sitwell all supporting Steve between you; the Hulk has Tony and he doesn’t seem to be having any trouble at all. Other than the occasional pause as one of you drops Steve to take out a roving enemy or two, though, the trip is actually fairly uneventful.
