A reply to 'Problems with modelling closed timelike curves as post-selected teleportation'

In arXiv:1107.4675 Ralph uses our post-selection model of closed timelike curves (P-CTC) to construct an "unproven-theorem" paradox, and claims that this voids our argument that P-CTCs are able to resolve such types of paradoxes. Here we point out that Ralph has not accounted for all the interactions needed for his construction. A more careful analysis confirms that indeed there is no paradox, contrary to his claims.
