My theroy is they find something strange in the hosbital and or they get to the roof and lock themselfs up there and its a race to fix the helicopter and escape the army below and or when there flying away angel pulls a cigar out and says "hosta la vista baby!'' -pulls out c4 detnator- "BOOOOOOM!!!!!!!!" and the hosbital crumbles to the ground! and kalani says "what the hell was that!!!!!" angel says "just tieing up some lose ends" -while the helicopter flys away into the sunset. no louder than a church mouse wisper angel says ''take that"
