Jaeger's judgment may have lapsed for a minute and probably cost him quite a bit in damage (if not trust from Winter), but when it comes down to the exact, necessary moment of action, he's there with fucking bells on.

The barrier solidifies around Penny, just a few scant feet from Winter, with expert precision and a semi-translucent glow that shimmers blue in the night air. It can be seen through vaguely, shadows and shapes, but it will prove to be as tough as concrete for as long as Jaeger can hold it. And he doesn't have to hold it long. Just a few seconds, ticking by like the roaring of his pulse in his ears as blood starts to drip from his nose.

It gives Penny those few seconds to realize exactly what's coming, and her scream of rage does carry through the barrier, that intense, horrible, perfect moment when she fully grasps her situation.
