Mutant Crush - S1-E4
Plot hole: With Jean's powerful telekinesis, she should have been able to untie herself from the chair.
Suggested correction: She would have to see the knots to untie them mentally. Blob could have used any number of ways to tie the rope off.
He didn't use rope, he bent a pipe around her so she should have been able to manipulate it.
Plot hole: In the end of the episode, Wolverine is seen recuperating after surgery removes the microchip in his brain, and his head is bandaged. Performing invasive surgery on Wolverine's brain isn't possible, since that would require going through his adamantium-infused skull and no conventional material is capable of that. Only a less invasive technique (such as going through the cranial sutres or cranial foramen) would have been effective and that most likely would not have required Wolverine's head to be bandaged (especially with his rapid healing mutant ability).
