Okay. I'm going to get this off my chest now. While I understand the symbolism of the deer and Riggs' mom, the actual shooting of the deer and watching it suffer was hard to watch.

I'm not sure if this was to move us towards disliking Riggs' dad, but the guy shooting a defenseless animal for no reason made me instantly dislike him. And I get the feeling that Riggs doesn't or didn't like his dad too much, either.

Lethal Weapon Season 2 Episode 4  didn't delve too deep into Riggs' past, but it did focus on other parent/child relationships like Nora and Cooper and Riana and Murtaugh. Avery and his relationship with Riggs and Murtaugh might even fall under that umbrella as well.

The highlight of all these was Riana and Murtaugh. 

Trish was out of town and Murtaugh tried to use the opportunity to bond with his teenage daughter.

It's not easy watching your kids grow up. It all goes by in a flash. One minute they're these tiny beautiful babies whose world revolves around their parents and then all of a sudden they're almost adults only wanting to be with their friends or anywhere other than with their parents.

Murtaugh wanted to know everything about what was going on in Riana's life, but Riana had no interest in sharing anything with her dad.

I had to laugh when Riana got arrested for protesting at the zoo. My 17-year-old feels the exact same way about those caged animals. And I feel the exact same way Murtaugh did. It's a zoo. That's why those animals are there.

Kids are funny that way. 

No matter how hard Murtaugh tried, he couldn't get through to Riana. She felt Murtaugh was the lamest dad ever. She felt he was hovering. She was embarrassed by his bad jokes. 

But that's what parents do when trying to connect to their teenage kids. We try to find common ground, but many times we fail. It's not the parents' fault; it's just the kids trying to separate themselves from their parents.

Murtaugh is a great dad no matter how lame Riana thinks he is. But the thing is that deep down she knows how great he is which is why she gave an inch and decided to stay in with her friends.

Even though Murtaugh didn't get to hang out with them (and what adult really wants to hang out with teenagers anyway?), he knew at that moment that he wasn't lame at all. Riana loved him, and that's all that mattered.

It was a beautiful moment made even more so when she wouldn't let him take the giant panda away. Deep down she knew she was still daddy's girl, and Roger knew it, too.

It's hard watching your babies grow up, but no matter how old they are, they will always be your babies.

Avery had the opportunity to move to a better place in the LAPD, but he wasn't about to abandon his babies. Roger and Murtaugh may cause him all sorts of trouble, but he could never leave them. And what would Murtaugh and Riggs do without Avery, anyway? 

The dynamic of their department would change drastically and not for the better!

I wasn't too fond of Santos's attitude towards anyone. She was hard on Avery, and he didn't deserve it, but in the end, she finally understood that as crazy as Riggs and Murtaugh are, they know what they're doing.

Riggs making that shot through Santos' arm was incredible. How could someone not respect that? Is it possible that Santos could be on her way out?

It's not that I don't like her, I do, I just like her and Murtaugh's dynamic better than her all over Avery. When did she turn into such a bitch?

I would have died if Avery had said he wanted to transfer out, but we knew that wasn't going to happen, right? 

The case of the week focused on another parental relationship between a daughter and her estranged criminal father. Seeing Adrian Pasdar was great, but Nora and Cooper's story was the weakest of the bunch. 

It provided a nice foundation for everything else, but it wasn't one of the better stories we've seen from Lethal Weapon.

And what was the deal with the boomerang rifle? How did Riggs' father die? Who gave the rifle back to Riggs?
