DI Hardy in last ep [SPOILERS]

I'd say it's 50/50 he makes it out if the series alive.

If he does die, I'd say it's about 50/50 it is his heart.

I am intensely anxious because either he dies of heart stuff, survives heart stuff to get killed some other way, or pulls through...and I have no idea which one.

I'd say this is as big for me as finding Danny's killer.
