"Reagan V. Reagan" pitted Erin and Danny against one another in a high profile murder case, but the it wasn't nearly as entertaining as watching the two fight like a couple of kids at the dinner table.

A defense attorney was killed in public moments before Erin stumbled across him. Somehow that murder didn't pack the punch for me that I felt it should have. Was it because the character used sleazy tactics in court? Perhaps, but it felt like there should have been more drama surrounding an attorney getting stabbed as he walked away from a trial.

What his murder did give us was the tension between Erin and Danny. For some reason, sibling rivalries never leave us no matter how old we get.

The confrontation about Danny's investigation felt off to me. I know Erin had a case she wanted to win, but Danny's job was to follow every lead and certainly the text the man received minutes before his death that told him to go to that bench qualified as such. Erin's anger at Danny for doing his job was irrational. She seemed to be taking it personally and losing her perspective because she didn't want to lose her case. I expected more from Erin.

The remaining defense attorney was smart to put Danny on the stand. She was building reasonable doubt. That's her job. Erin's tough cross examination was a justifiable response to that.

The funny part was when the two siblings went head-to-head over Sunday dinner. They argued while passing potatoes and corned beef. They bickered like a couple of kids, causing Henry to comment that it was as though they were 10 and eight all over again. Frank shot back that the behavior was bad enough when they actually were 10 and eight and Jamie wondered what everyone else had to complain about, as he was the one who was always stuck in between the two in the car as they fought.

I might not always think that Blue Bloods gets the investigation or the court scene just right, but it portrays family life so well. Henry even sent the quarreling siblings off to do the dishes as punishment.

Frank, meanwhile, had other issues, as he wondered whether an old friend was involved with a credit card scam. How stupid do you have to be to scam the Police Commissioner's credit card? However, I suppose they did get away with it for a while. 

The best part of that story was how matter of fact Garrett was about the whole thing. I especially liked it when he told Frank to charge the house Scotch instead of the expensive stuff.

I did wish we'd gotten to see Frank's birthday dinner but, then again, I doubt they could do much better than the standard Reagan Sunday meal.
