Damage

While dissension among Xindi ranks festers, Degra gets Archer returned to Enterprise. Archer considers compromising his morals to restore Enterprise's warp capacity after a fleet of Xindi-controlled warships cripple the vessel's engines. Sacrificing his ethics, he attacks an innocent alien ship to get their warp coil to repair the Enterprise's engines and intercept the Xindi superweapon.
