Express and Jade, passing in variables

I'm trying to install this captcha plugin and this is what I have so far (straight from their code, just kind of tweaked up to my style)

Here is captcha and steps I'm following: https://github.com/mirhampt/node-recaptcha

In my router.js file:

app.get('/account/verification/:token/', require('./views/account/verification/index').verifyHuman);

In my /views/account/verification/index.js file:

exports.verifyHuman = function(req, res, next){
  var Recaptcha = require('recaptcha').Recaptcha;
  var recaptchaKeys = req.app.config.recaptchaKeys;
  var recaptcha = new Recaptcha(recaptchaKeys.publicKey, recaptchaKeys.privateKey);

  console.log(recaptcha.toHTML()); //this returns a script tag with an iframe and stuff in it

  res.render('account/verification/captcha', {
      layout: false,
      locals: {
          recaptcha_form: recaptcha.toHTML()
      }
  });
};

and then my /views/account/verification/captcha.jade file:

      div#captcha
  script(type='text/template', id='tmpl-captcha-verification')
    form#captcha-verification
      #{recaptcha_form}

      button.btn.btn-primary.btn-captcha-verification(type='button') Check Captcha

I can't get it do display the captcha script. It comes up as undefined but in a strange way. This is what appears in my console:

<script type="text/template" id="tmpl-captcha-verification"><form id="captcha-verification"><undefined></undefined><button type="button" class="btn btn-primary btn-captcha-verification">Check Captcha</button></form></script>

I can even try and do #{layout}, and I get this in the console:

<script type="text/template" id="tmpl-captcha-verification"><form id="captcha-verification"><false></false><button type="button" class="btn btn-primary btn-captcha-verification">Check Captcha</button></form></script>

It's like jade is trying to format it, but one of the main issues is that it's undefined, when the variable in my /views/account/verification/index.js file that I console.log isn't.

Also, note that if I do != recaptcha_form, it just shows the form in the html as it would if this != recaptcha_form code wasn't even there.

I've searched around other questions for this answer and am still pretty confused. Any help would be greatly appreciated. Thanks
