Welcome to the Family Part 2 - S2-E25
Revealing mistake: When the family releases Chloe's bubble ability for the last time in the episode the bubble machine is visible.
Suggested correction: There is no bubble machine visible.
Continuity mistake: When Phoebe and Max are tied together, the whip starts to cause sparks to fly in the the air. Then, a lightning bolt appears and Electress (really Barb) pops up and says "shocked to see me?" and the whip isn't sparking anymore.
Suggested correction: Her presence stops the whip from sparking as it was her weapon.
But wouldn't the fact that Max and Phoebe are touching the whip also keep it from sparking? True, it's not their weapon, but they are "supes," so their powers should have prevented it.
Continuity mistake: When Max and his band are at Splat Burger in the beginning, the table that the band is sitting at changes. When Max introduces the band to Wolfgang, they are sitting at a booth near the door. When Max gets up to play his song, they are sitting at a booth in the middle of the restaurant. When Max is covered in tomatoes, the band is at the booth by the door again.
Suggested correction: I can't find it; I don't think they move. W.
