Joe lifts up, though not with the same sort of ease that Steve does; he's clearly still in his prime, while Joe is already starting to leave that behind, though at least the armour hides that his muscles are starting to run to fat. Still, he's determined not to show weakness, not here, not in front of these strangers, when there are actual monsters clawing to get in.

"There haven't been rainstorms in decades." Joe replies, but there hasn't been green like there is outside the diner in decades either. Something is definitely not right, but Joe hasn't had time to dwell on it. "The birds may not be the only danger. Are you armed?" Steve has that shield, but a defensive weapon will only get them so far. If need be, he can loan Steve his .357, but his ammo is limited, and Joe is loath to expend resources needlessly.
