Electrons behave as both particles and waves regardless of velocity. My conclusion from the fact that a single electron still has an interference pattern, is that until they interact with a detector and collapse, they are waves- even a single electron. So a single electron in its wave form (pardon the pun) will pass through both slits.

It's the waves that interact with each other- waves from or of the same electron. When the waves hit the detector, at high speeds, they become a particle. The location of the hit is random.

A single electron does not form the interference pattern. We have to sum over many electrons, all arriving singly, in order to get the interference pattern. So in this case, a single electron has both wave and particles properties.
