Meredith and Penny

Anyone else think that Meredith had a right to be mad at Penny. Like I know Penny didn't kill Derek, but she was one of the people that made it possible for Derek to die. If Penny had pushed more for the Head CT, Derek might not have died. Penny's inaction helped lead to Derek's death.

Because of Penny's inaction, the love of Meredith's life and the father of her kids died. Meredith has a right to be mad. Anyone in her position would be mad or at least hold some sort of grudge.

Two people that really pissed me off about the whole situation were Richard and Callie.

Callie gets mad at Meredith for being mean to Penny, but if Callie were in Meredith's place she would have done the exact same thing. Also the only reason Callie cared about how Meredith treated Penny was because Penny was her girlfriend.

And then there's Richard. Richard really told Meredith to not get mad at Penny, when in Season 9 he yelled at one of the nursing facility staff members for telling him to not visit Adele as often (If Richard had visited more often, he might have found out about Adele's tumor).
