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 θ¹ Ori B₂, so it may have been deflected by the wind/radiation from the nearby θ¹ Ori B₁B₅. The origin of both components is unclear, but if each of them is a separate jet, then θ¹ 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 θ¹ Ori B₂B₃ does not directly face θ¹ Ori B₁B₅, suggesting that the EUV radiation from θ¹ Ori C plays a dominant role in affecting the morphology of proplyds even in the vicinity of θ¹ Ori B₁B₅. Finally, we report an Hα blob that might be ejected by the binary proplyd LV 1.
