Complete the supervillains' conversation as they bond over their lack of basic evil skills. Drag the correct words into the blanks.

Villain A: "I can't seem to build a working laser."
Villain B: "Honestly, neither can I! It always explodes."

Villain A: "I don't understand how to trap a hero properly."
Villain B: "My sidekick says I don't either. They always escape!"

Honestly, neither can I! It always explodes.

To agree with a negative statement ("can't build"), we use "neither + auxiliary + subject". The auxiliary must match the modal verb "can" used in the original sentence.

My sidekick says I don't either. They always escape!

Another way to agree with a negative statement is "subject + negative auxiliary + either". We use "don't" to match the present simple negative verb ("don't understand") from the first sentence.
