Quick question regarding variable registration

[Mythotical]

Does anything in this need to be registered or pre-registered?

Plugin hook location - profile_start:

PHP Code:

if ($_REQUEST['do'] == 'ignoredthreadslist')
{
    construct_usercp_nav('ignoredthreadslist');
    $navbits[''] = $vbphrase['ignored_threads_list'];
    $templatename = 'usercp_ignoredthreadslist';
}

if ($_REQUEST['do'] == 'ignorethread' || $_REQUEST['do'] == 'unignorethread')
{
    $templatename = 'bogus';
} 


How would I preregister variables without having to use a created template?

This looks more correct to me:

if ($_REQUEST['do'] == 'ignoredthreadslist')
{
    construct_usercp_nav('ignoredthreadslist');
    $navbits[''] = $vbphrase['ignored_threads_list'];
    $templater = vB_Template::create('usercp_ignoredthreadslist');
    $templater->register_page_templates();
    $templater->register('templatevar',$templatevar);
    $templatename = $templater->render();
}

if ($_REQUEST['do'] == 'ignorethread' || $_REQUEST['do'] == 'unignorethread')
{
  $templater = vB_Template::create('bogus');
  $templater->register_page_templates();
  $templater->register('templatevar',$templatevar);
  $templatename = $templater->render();
}

Thanks BBR-APBT, now the question I added was how to preregister variables without doing all the template creating of a custom template, etc?

And I have read this thread https://vborg.vbsupport.ru/showthread.php?t=228078 multiple times but it doesn't mention doing preregister without having to register a created template.
