Picture a situation where two black holes are moving in opposite directions at just a fraction under the speed of light. Their event horizons are length contracted so much that they practically become discs rather than spheres. The two black holes pass each other in such a way that at the point of closest approach the edges of the two discs pass through each other. (Picture one moving towards you and the other moving away, and imagine them side by side as they pass each other - both should be deflected sideways by each other's pull, and the amount of that deflection will be related to how fast they're moving.) Now, if we have a photon moving perpendicular to that action (you should visualise this as moving straight upwards) such that it passes through the edge of both discs exactly at the moment when they pass through each other, it won't be directed towards either black hole and should just continue on up the same path as it was on before, exiting both event horizons simultaneously.
