What is the best way to choose a specific item from one array in AngularJS and then incorporate it into another

I need assistance as I am confused about how to select a specific item that originates from a different array. If selecting an item from another array is not feasible, then is there a way to locate and choose an item within the current array? Could you please provide an example if this is possible? PS: I managed to set an item by choosing it directly from an existing item, like so, but I wish to be able to pick it from a separate array.

$scope.initialMention = [             
              $scope.mentions[0][0],
              $scope.mentions[1][0]
];

var app = angular.module('plunker', []);

app.controller('MainCtrl', function($scope) {

      $scope.mentions = [
          [
