Cedric does catch on. He's seen Howard stuff his face too many times to not be suspicious.

"I'd find a way, somehow. Making a large sound, or attracting attention some other way. Unfortunately, I never learned how to Apparate."

He sighs. That would've been even more useful. "But I will find something. We've gotta get out of here."

The worse Howard looks, the more Cedric worries. Something's really wrong, it must be.
