Question: I never really understood the point of injecting the needle into your heart if you come into contact with the chemical. Doesn't the chemical eat away at your skin?

Question: In the opening scene, when Hummel passes the four soldiers in the graveyard he salutes them but they pay him no attention, even though he is a general. I was thinking it could have been because they are taking part in the funeral procession, even though Hummel probably couldn't tell that, as they weren't carrying the coffin anymore at that point. Also, it seems a bit strange for a funeral as they're not victims' family or any other participants. Is there any explanation for this?
Question: When did Mason have time to write the note of the location of the secret stuff? He surely didn't have it on himself all the time due to the risk of being frisked and that it had no water damage.
