9- "I am so glad I met you." Because it shows their amor is so deep but simple. They don't need grand gestures o poetic speeches to mostrar how much they amor each other.
Donna- "He deserved it... No, he didn't." the moment Donna estola my heart! Forgiveness is important, especially to your enemies, and this shows Donna is a very strong person, willing to forgive even after getting emotionally shot in the heart.
Rose- "Yeah, but being stuck with you- that's not so bad." See 9's descripción (even though it applies to 10). I related to it, relationship-wise.
I have 2 favorito! characters, so they'll just share :D
Martha's- "I spent a lot of time with tu thinking I was segundo best, but tu know what? I am good." - Inspirational af. That's one to go on the pin boards. Reinette- "One may tolerate a world of demons for the sake of an angel"- It's practically a cliche at this point, but it still does ring true today. And the way she says it! These aren't my favorito! quotes, but they're my favorito! from my two favorites.
