New additions - one possibly building?

So I've been wanting to get a rack for a while now. Yesterday, I happened upon a local ad for racks and snakes, and made an offer on the rack. Today, I came home with a rack and two females - one normal adult and a juvenile fire (who's dad was supposedly a Mike Wilbanks fire! )

The seller had paired the normal girl with a firefly and a pastel lesser, last pairing about two months ago. He suspects she is building, but isn't sure. I'd love to hear your thoughts!

And here is the fire, who is just out of a hunger strike:

Forgot to include weights! The normal girl is 2000g and the fire is ~660g.
