Felix becomes one of Peter Pan's most loyal Lost Boys and lieutenant. He searches for the heart of the truest believer for Pan. When Baelfire arrives in Neverland, Felix and the Lost Boys abduct him but find out that he isn't the one Pan wants.
When Greg and Tamara arrive in Neverland with Henry, it is revealed that the mysterious "Home Office" was actually the Lost Boys. Felix tells the two to give Henry to them, but when they refuse to co-operate, Peter Pan's shadow arrives and kills Greg, before one of the Lost Boys shoots Tamara with an arrow. When Henry is saved and Pan is seemingly defeated, Felix and the other Lost Boys are taken back to Storybrooke with Henry's family, where they are given a chance to live without Pan's rule. However, Felix stays loyal and when he finds Pan again, he helps him try to enact the Dark Curse. When Pan says that he needs the heart of the thing he loves most, Felix thinks it is Pan's son Rumplestiltskin, but he is shocked to find out that it is actually him. Pan rips out Felix's heart and crushes it, killing the only person left who was loyal to him.
