名探偵コナン » Volume 24 » Page 160

To allay Haibara’s fears of being recognized at an event, Conan lets her wear his fake glasses as a disguise. After she’s kidnapped, Conan communicates with her through the wireless communication device built into the glasses, in hope of discovering where she’s being held. Once Haibara confirms she cannot escape the room she’s in, she tells Conan to listen carefully and starts listing off the details of her research around the drug that caused the two of them to become children.

コナン:
「おい、やめろ!! んな(こと)おまえがそこから脱出(だっしゅつ)したら()いて…」
“Hey, stop it!! I'll listen after we get you out of there...”
灰原:
いいから(だま)って()きなさいよ!!」
Just shut up and listen to me!!”

Key Points

  1. いいから = “enough with that”

    • In this scene, いいから does not mean “because it’s good” or “it’s fine” literally. It is a forceful way to cut off what Conan is saying and push the conversation forward.

    • Here it works like “Enough, just…” or “Just…” before the command that follows.

  2. The line is really two commands

    • いいから (だま)って ()きなさいよ」 is basically “Stop arguing about that, be quiet, and listen.”

  3. 黙って links into the next action

    • (だま)って is the -て form of (だま), so it connects to ()きなさい.

    • The sequence is “be quiet and listen”, not two unrelated fragments.

  4. 聞きなさい is a firm order

    • 〜なさい is a commanding form often used when speaking down to someone, scolding them, or giving a strong instruction.

  5. Sentence-ending adds insistence

    • The final pushes the command at the listener and makes it sound more emphatic.
