If you use the print_r function to find out what $obj2->Comment contains, you will see that is is an array of stdClass objects. So to add in addtional entry, create a stdClass object, set its values, and use array_push to add it to the collection. Here is an example:

$rebuttal = new stdClass;
$rebuttal->Name = "Garfield";
$rebuttal->Comment = "I hate Mondays!";
array_push($obj2->Comments, $rebuttal);

P.S. I am ignoring the sytax error in your json file.
