When Angel turns into his demon self and attacks the guard, a close-up shot shows him tear the man's leg off at the knee. Immediately after, in a wide shot (where the other guards ride away), his legs are both clearly intact. Another shot of the body later shows the leg missing.
When Lorne and Angel go to meet Lorne's mom, there's a cardboard box with a red top, and a yellow object in the lower left corner of the screen next to the tree. In the reverse angle the object disappears, but reappears in the wide angle of Angel and Lorne walking up the hill.
