I agree that there really isn't a place for Natalia to tell Samantha to quit. Was there an episode that I may have missed that promoted Nat or somehow made her the Lab Queen above everyone?? She's no Mac Taylor. And, at first I wasn't really warming up to Walter until he convinced Sam to stay, pulling her aside like that. Hehe. I'm starting to enjoy watching Walter more. As for Sam, I thought that it was that Sam from Sunblock until I heard "new girl". It's nice that Walter admits that people do make mistakes. But, I'm about done with the misses and errors among the CSIs that makes them go rogue or judgemental at times until they realized that they had missed something in the end. Examples like Alex believing that a guy poisoned his girlfriend in Bad Seed, Tom and Calleigh believing that a dead mother was drinking in Point Of Impact, and I think it was Ryan who said something to Eric about the guy injured during the tornado in Blown Away. Funny the lengths that Eric goes to just by anything his CSI buddies would tell him. He came back after Jesse's death with this?? And now Natalia missing out something that Sam found. Odd for someone with the ability to find sweat on a leaf in Bang, Bang Your Debt. As much as I would like to see character development rather than misses or the job's demands that makes them go loony-bin loco, I expect better and more respectable writing as well as consistency that the CSIs are actually professional and not all promptly rogue until they realize their own mistakes or misses in the end. Somewhat making Horatio write "unsolved" on the box. It makes the characters look more incompetent as the writing continues to be purposely shitty from time to time. If it wasn't for rogueness, incompetency, misses, and all around vigilance, and more scientific processing, cases would've been solved better and the killers would've been found. I'm loving Ryan's scream about staining his shoes. And Calleigh stopping the guy = cool. And I also enjoy Ryan's and Walter's funny exchanges. Their friendship has got to be one of the greatest CSI-based friendships ever! This episode gets a C-.
