Don't worry, just hurry with いいから

Vocabulary Explanation: Don't worry about it with いいから

Wolf spends some time with Mia, a young girl who’s run away into the forest. After hearing about the troubles Mia is facing at home, Wolf hears something in the distance. She tells Mia to go with her.

みあ:: 「どこ行(い)くの？」; “Where is it that we're going?”
オオカミちゃん:: 「いいから早(はや)く！」; “Don't worry about that, hurry!”; Literal: “It's fine, so hurry!”; 「こっちこっち」; “This way!”

Key Points

1いいから = don’t worry about that

Here, いいから tells Mia not to focus on her question about the destination and to move now instead.
It often works like “it’s fine, so…” or “never mind that, just…” depending on context.

2Implied continuation: いいから、早(はや)く行(い)こう

The line is short because the rest is understood from the situation.
That blunt shortening makes the line sound urgent rather than explanatory.
