Detect which block method (_prepareSpecificInformation) is in use

Question

I have created a payment method and it has a _prepareSpecificInformation() that is extended under the Mage_Payment_Block_Info. Just need to detect where this is being called from with in the function as there are some points that I want to show everything and others, like an email, that I don't. This is what I have now.

protected function _prepareSpecificInformation($transport = null){
    $helper             = Mage::helper('centralprocessing');
    if ($this->_paymentSpecificInformation !== null) {
        return $this->_paymentSpecificInformation;
    }

    $info = $this->getInfo();

    $transport = new Varien_Object();
    $transport = parent::_prepareSpecificInformation($transport);

    $transData=array();

    $transData[Mage::helper('payment')->__('Card Type')]=$helper->getCardType($info->getCardType());
    $transData[Mage::helper('payment')->__('Masked CC Number')]='############'.$info->getMaskedCcNumber();

    $transData[Mage::helper('payment')->__('Response Return Code')]="".$info->getResponseReturnCode();
    $transData[Mage::helper('payment')->__('GUID')]=$info->getResponseGuid();
    $transData[Mage::helper('payment')->__('Approval Code')]=$info->getApprovalCode();

    $transport->addData($transData);

    return $transport;
}

So I wanted to add conditions on what is added to the $transData array depending if it's the admin or if it's in the email and such.

UPDATE The reason is that I need to put a link in with the data in the admin page only. Also turns out that

$transData[Mage::helper('payment')->__('GUID')]="<h1>HELLO</h1>";

Prints <h1>HELLO</h1> so the html is escaped first?
