so assuming that something and somethingElse return promises, the return value of the callback passed to .then() will return either a promise, or undefined.

is this ok? i'm paranoid that an error is going to get thrown and won't get caught.

also: i'm using q, and if i want to ensure that any exceptions thrown are caught, i would need to add a .end() after the .then() correct?

It's perfectly ok. The final result would be undefined or resolved value of promise returned by somethingElse. Test it :-)
