Suppose I have a MacBook and want to back up occasionally to an external hard drive.

In between external backups, would Time Machine be backing up file versions on my internal drive? If so, how would that work in times of size?

TM can not backup the drive it is located on. Since a Macbook has one internal drive, TM has to backup to an external drive. If there is no TM drive available, no backups will be made until until one is.
 
Time Machine requires an "external" drive so there's no way it would back up the internal since the internal has all your info already.

So it will keep versions only for the days that you backup, right?
