 Alias has some references to “Alice in Wonderland”. For instance,  when Sydney returns from her two year absence, she moves into a new  house since the old one burned down. Weiss asks her what is the one  thing she wishes she hadnt lost (other than Vaughn), she says the  first edition of “Alice in Wonderland” that her mother gave when she  was little. So Weiss gives her a third edition (because he says the  first edition cost way too much) to make her feel better. This is  interesting because Sydney is an Alice herself going deeper and  deeper into the rabbit hole. In season 1, Sydney dressed up like  Alice for Halloween; in season 4, Vaughn is directed to "through the  looking glass" when he is searching for something in the library,  and in the season 1, Vaughn has a girlfriend named Alice.
