Rite of Passage

Cassandra collapses on the night of her birthday. She is then brought to the SGC by Janet Fraiser and Samantha Carter. She starts exhibiting telekinetic abilities and is generating EM fields. She is also screaming things like "I have to go into the forest." SG-1 travels to Hanka to find out what is happening. They search the forest on Hanka and find a glowing handprint and fire logs. Daniel Jackson puts his hand on the handprint which activates a fire. After they go near the fire a Ring transporter takes them to Nirrti's lab. They go back to the SGC with several devices they have found in the lab. It turns out that Nirrti has been hiding in the SGC using a cloaking device. SG-1 captures her and makes a bargain for her to cure Cassandra in exchange for her freedom.
