When you check back with Felix after he tells you it needs a gear, he then writes a company and phone number on a scrap of paper and hands it to you. If you then ask him if he can order the part, he replies, "Sorry, never heard of that company".
Eh…?! He wrote it down not two seconds earlier - now he's never heard if it…?! I honestly don't think he should be trying to hold down any kind of job if his memory's that bad, presumably he must kip on one of the beds behind him because he'd never find his way there!
By the way, are Felix, Oliver, Ronald, the tailor and broker a set of identical quintuplets…? Or, perhaps only one of them really exists - Oliver could be a hologram and, as you cancan only be in one shop at a time, the rest are actually all Felix. Or clones.
