After the helicopter failed to break out Whistler, Sona’s new commander, Panamanian general Zavala, decides to make Michael talk by putting him into the sun-exposed isolation hot-box, promises to help in exchange for the truth, verifies the L.J-situation and is told it’s about Whistler, who already realized the tunnel is a no-go without engineer Scofield but denies blatantly to Zavala- and is threatened with torture until he admits to collaborating with Michael, who convinces him next to give up Gretchen Morgen’s name.
