Two months later
On the far side of the moon, at the Plumbers' Watcher Space Station.
Beneath the massive dome, Steve Rogers wore a futuristic black Plumbers skintight combat suit. Holding a shield made of high-density photon energy, he sweated away on the training grounds.
"Left, Bucky!" Steve shouted.

"Berlin." Jiang Li's expression darkened. "When I crippled Ross's base, some nano liquid metal may have been left behind in the servers."
