Kira and Odo are returning to Deep Space Nine in a runabout. They just visited Prophet's Landing, a colony close to the Cardassian border, to review security procedures. When they receive a distress call from a Lissepian supply ship that was attacked by a Maquis one-man vessel, they start to follow the Maquis. The ship lands on a moon and Kira and Odo follow him into a very unstable cave. Kira's foot gets stuck in a strange crystal. While the crystal slowly encapsulates the major, Odo tries everything to free her. Meanwhile Nog makes a special request to Sisko. He has become an adult and is ordered by Ferengi by-laws to purchase an apprenticeship from a suitable role model. Nog wants to be the first Ferengi in Starfleet and asks Sisko to write a recommendation for the Academy. Written by Arnoud Tiele (

Nog: My father is a mechanical genius. He could've been chief engineer of a starship if he'd had the opportunity. But he went into business, like a good Ferengi. The only thing is, he's not a good Ferengi - not when it comes to acquiring profit. So now, all he has to live for, is the slim chance that someday, somehow, he might be able to take over my uncle's bar. Well, I'm not going to make the same mistake. I want to do something with my life, something worthwhile.

Two important plots get a strong push in this episode.
22 December 2014 | by (Bradenton, Florida) – See all my reviews

Only a few episodes after this, Major Kira and Odo would begin a love affair. Additionally, Nog would eventually become a crew member--a loyal one at that. Both these new plots get huge send-offs in "Heart of Stone".

When the show begins, Nog asks Commander Sisko if he could recommend him to Starfleet Academy! Considering Nog's history as a thief, this is a very tall order and to get him out of his hair, Sisko gives his a task to do. Nog does a great job and Sisko has to decide what to do next with the eager young Ferengi.

At the same time, Major Kira ends up being encased in crystal and appears to be slowly dying. Despite her protests, Odo won't leave her and stays with her--trying to free her as well as trying to ease her suffering. Eventually, Odo admits to her that he is in love with her! But then there is a HUGE twist...but I'll say no more.

This is a very interesting episode and I am glad both plots were introduced. Worth seeing.
