Overcoming the Clashing Tides/Heartwarming

When Alex tells Drake off, showing that she really loves and cares for her brother.

Alex: "Because I care about you, idiot! Listen to me, Drake! Don't you dare think that you're the only hurting! What about Lewis, huh? He just lost two members of his family! Don't make this all about you! You weren't the only one that cared for Maria and Ashley! Jay may be denying it at the moment, but he loves Ashley the way you love Maria! Lizzie was practically Maria's sister! How do you think she's coping? Just because she keeps on that ridiculous cheery smile on her face twenty-four/seven doesn't mean that she isn't hurting at all. And I- Ashley was my...best friend. And it kills me on the inside to see you so depressed. Don't become like Dad when his dad left after Grandmother's death. Please... This isn't you.

Ronnie comforting Rory when she finds out that she is Drake and Alex's younger sister and Alex shuns her because of it.

Ronnie: "Couldn't sleep, huh?"
Rory: "Yeah... How did you know?"
Ronnie: "Intuition."
Rory: "Um, Ronnie, is Alex always so-"
Ronnie: "She's just upset. Alex has always been the mature one. She forced herself to grow up quickly for some reason. If you want the real story, you should ask Drake."
Rory: "She never treated me well before, and now..."
Ronnie: "Alex doesn't like letting people in. She's built up walls around her. I think that's why Ashley always annoyed her; it was the only way for Alex act childishly. Look, Rory, I know you're very confused about Alex, but you have to be patient. Alex may, no, is difficult, but she has a heart of gold behind those walls. Just hang in there, alright?"
Rory: *moments later* "Thanks, Ronnie. For everything."
