Why is User.follow only available in two view? - node.js

Question

I'm using Passport to authenticate my users and pass their information to every view, beside the information stored in the user database. I'm trying to pass the friendship information related to the user (logged in user). The problem is that this only works in two of my views:
Single User page
//info is the profile information of a registered user
<%= info.profile.fullname %>
<br>
<%= info.email %>
<br>
<%= info.profile.country %>
<br>
<%= user.follow %>// just for testing
<br>
<% if(user && (user._id != info.id)){ %>
<br>
<form action="/follow/<%= info._id %>" method="post">
<button type="submit">Follow</button></form>
<%}%>
<br>
atras
List of Registered User
<%if (user) {%>
<h1>Hola <%= user.profile.fullname %> </h1>
<%}%>
<br>
<% users.forEach(function (user) {%>
<p><%= user.profile.fullname %></p>
<%});%>
<%= user.follow %>// just for testing
Home
This is my index and in this view the user.follow doesn't work
<%if (!user) {%>
sign up
<br>
login
<%} else { %>
<h1>Hola <%= user.profile.fullname %> Eres lo Maximo</h1>
perfil
<br>
Logout
<br>
<%}%>
<br>
Lista de Usuarios
<%= user.follow %>// just for testing
//in this view i got undefined
deserializeUser config.
passport.deserializeUser(function(id, done) {
User.findById(id, function(err, user) {
FF.find({ follower:id }, function(err, follow) {
user.follow = follow;
});
done(err, user);
});
});
This is my route code
router.get('/', function(req, res) {
res.render('index');
});
router.get('/login', userController.getLogin);
router.post('/login', userController.postLogin);
router.get('/logout', userController.logout);
router.get('/signup', userController.getSignup);
router.post('/signup', userController.postSignup);
router.get('/profile', passportConf.isAuthenticated, userController.getAccount);
router.post('/profile', passportConf.isAuthenticated, userController.postUpdateProfile);
//Test Usuarios
router.get('/users', friendController.getListUsers);
router.get('/users/:id',friendController.getShowUser);
// Test Follow
router.post('/follow/:id', passportConf.isAuthenticated,friendController.postFollowUser);
