When Prue and Phoebe rescue Tessa from the cage and take her to the manor she has a small cut on her right cheek but by the time they arrive at P3 the cut is gone.
Prue tries to relieve her boredom by using telekinesis to position a vase on the mantle. When the vase is first seen it is positioned on the left; it cuts back to Prue waving her arm, and then the vase is shown on the right side of the mantle moving to the left.
The snake shown at the beginning has red bands next to its black bands which means the snake is not venomous. The remainder of the episode focuses on the snake being venomous.
When the snake and the rabbit are at the manor, they say that there are four hours left until the spell wears off. There is visible daylight in the windows at this time.
Later, at P3, Phoebe says the spell will wear off at midnight, making the time that the snake and rabbit were at the manor 8:00pm. Since the episode takes place during Valentine's Day (in the winter), it would be dark at 8:00pm.

When the men/animals leave the students' room for the first time they are supposedly wearing nothing, but when the Snake knocks down Ethan and turns to leave you can clearly see he's wearing boxers.
