dumbledore: harry, getting this memory is literally the most important thing in the entire universe. it has to be your number one priority. it is crucial. imperative. it is the key to defeating lord voldemort and there is literally no point in continuing without it
ron and hermione: harry! why don't you use your lucky potion to do this thing that is the absolute most necessary and important thing you could possibly do? what on earth could possibly be more important to you than getting this memory?
harry: hmmm... i don't know... maybe asking out ginny weasley *dont tell ron I said that*
