All the best lines are straight from the book:
^"My sword's yours, then … but don't go looking for me to bend the knee and m'lord you every time you take a shit. I'm no man's toady."
"Nor any man's friend," Tyrion said. "I've no doubt you'd betray me as quick as you did Lady Stark, if you saw a profit in it. If the day ever comes when you're tempted to sell me out, remember this, Bronn—I'll match their price, whatever it is. I like living. And now, do you think you could do something about finding us some supper?"^ AGoT Tyrion VI

Bronn is one of my least favourite book characters. He is an absolute arse with absolutely no moral compass. Show Bronn is totally different. I really could see book Bronn killing one of the Lannister brothers - it’s totally in character for him to do so. I can’t see it with show Bronn. He’s been portrayed as far too ‘nice’ for several seasons.
My prediction is that he’ll be ‘taken down’ at the crucial moment by Pod.
