Im going to do this for the last time. There are three potential roles being tossed around right now and while I sit on the crapper at work, I will go step by step.

The three roles. Redirector, bus, roleblocker.

Some facts claimed by players.
Pass sent brett an item.
Brett denies receiving said item. This means brett cannot be a bus because busses cannot bus themselves.
Pass could have been bussed but that would not effect his ability unless he was bussed with the person he sent the item too. Which is not possible given what we know.
Pass could have been the victim of a redirect but I do not think that is the case.
That last part is actually irrelevant as we have only two possibilities, given what we know. There is both a redirector and a roleblocker or one of them is lying or witholding night results.

The problem I have with cybers post is that he is fishing for more roles when it isnt needed.
