Maul circles warily as Undyne hefts the cot and then hurls it towards him. Then he makes an error; it's instinctual, really, after a lifetime of Force sensitivity. As the cot is hurled towards him, Maul's arm shoots out, hand open to telekinetically grab hold of it and either toss it aside or, more likely, back at Undyne. Only too late does he remember his connection to the Dark Side has been severed and the gesture is pointless.

At which point the cot beans him in the head and he's knocked back, stunned with an angry snarl of pain.
