I don't blame Barnabas for that. If David does spill the beans about Barnabas, it is total, absolute disaster for Barnabas. An ounce of prevention is worth a pound of cure.
Barnabas is SO cool... so cool in fact that we can throw in our lot with him... or his... when he's being a killer. I love the blurring of boundaries and reappraisal of morals. And given that BC has opted for survival, a goal for many of us, given that absolute, he has to off David. It oughta trouble him though. His big internal claim to legitimacy is his loyalty to family.
Lydia, I'm not claiming you harbor murderers in your basement or anything.... there are blurred boundaries, possibly, but that can be the sign of a free thinker.... and I'm interested and uninformed (and know it) as to how far it all might go....
