9- "I am so glad I met you." Because it shows their प्यार is so deep but simple. They don't need grand gestures या poetic speeches to दिखाना how much they प्यार each other.
Donna- "He deserved it... No, he didn't." the moment Donna चुरा लिया 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 विवरण (even though it applies to 10). I related to it, relationship-wise.
I have 2 प्रिय characters, so they'll just share :D
Martha's- "I spent a lot of time with आप thinking I was सेकंड best, but आप 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 प्रिय quotes, but they're my प्रिय from my two favorites.
