Avram is the nervous young man given the important task of looking after it, and apparently he needs a gun to do it.
2. Peter Connelly is in trouble
Being the last person seen with a young woman who turns up murdered the next morning is not a good start, but not telling the police and trying to take on the investigation yourself is rarely going to improve matters. Things can presumably only get better for Peter. Or not.
3. There is something big happening
Prophesies, red heifers, mysterious deaths, REM quotes. All of this says that DIG is going to some very exciting places in the next 10 weeks.
