Sad, But Excitedly Nervous!

It's going to be sad to see my "former" companion go.  She is a great companion.  She is a very hard worker and has really made this area great.  I'm excited though, to train.  I'm also really nervous.  I heard training is super hard.  I don't know ANYTHING about my new companion - not even her name.  I find all that out during transfers.
