Underscore

File 1:
_ = require('underscore')._;

Controller.prototype.loadInit = function( controller ){
	if(controller[1] in this.models){
		this.model = this.models[controller[1]];
	}
	var req = {
		sockets: 		this.sockets,
		controller: 	controller[1],
		utils: 			this.utils,
		library: 		this.library,
		app: 			this.app,
		config: 		this.config,
		db: 			this.db,
		models: 		this.models,
		model: 			this.model,
		_:  			_
	};

	controller[0].init(req);
};

File 2:
module.exports = {
	init: function(req){
		console.log(_);
	}
}
//I want to use _ inside the init function without having to redefine underscore in file 2
