We present Magellan adaptive optics Hα imaging of HH 508, which has the highest surface brightness among protostellar jets in the Orion Nebula. We find that HH 508 actually has a shorter component to the west, and a longer and knotty component to the east. The east component has a kink at 0.″3 from the jet-driving star θ 1 Ori B2, so it may have been deflected by the wind/radiation from the nearby θ 1 Ori B1B5. The origin of both components is unclear, but if each of them is a separate jet, then θ 1 Ori B2 may be a tight binary. Alternatively, HH 508 may be a slow-moving outflow, and each component represents an illuminated cavity wall. The ionization front surrounding θ 1 Ori B2B3 does not directly face θ 1 Ori B1B5, suggesting that the EUV radiation from θ 1 Ori C plays a dominant role in affecting the morphology of proplyds even in the vicinity of θ 1 Ori B1B5. Finally, we report an Hα blob that might be ejected by the binary proplyd LV 1.
