Sam who?

[The Only Real Estel]

aragorn thought that gandalf would atomaticaly think sam went with frodo so didnt bother mentioning him, so sam (like his name) just slipped gandalf`s mind.

So did Aragorn & co. have to totally refresh Gandalf's memory? If so, with Gandalf remembering no one's names, they would've had to explain Frodo, & most likely he wouldn't forget to mention Sam. Oh well, no one really knows...
