You need to add the Expendables storming the place, blowing the whole hospital, and then as the smoke clear, a mysterious figure, surrounded by the Expendables, who are securing Berry's room, sole surviving part of the hospital, appears, and, surprise, surpirse, it's the G-man from the Half-Life videogame series!
G-man: "Wake up, Dr. Freeman. Wake up and... smell the ashes!"
Berry: "My... My name is Freeman?!"
G-man: "Ye- wait a moment!" (takes out some papers from his briefcase, looks at them, confused and puts them back inside the briefcase, embarassed) "Well, um, there seems to have been a small confusion here, ...um..., we apologise for any incomvinience we may have caused."
Sylvester Stallone: "Speak for yourself!"
G-man: "Whatever, pack it up, boys, we got the wrong place!"
