The Seed

"The Seed" is the second episode of the fifth season of Stargate Atlantis.

Plot
When a mysterious alien organism takes Dr. Keller as its host, Beckett and the crew desperately search for a serum to save her from the evolving intruder before it can infiltrate Atlantis.

After 2 months in stasis Dr. Carson Beckett is finally revived when Dr. Keller discovers the serum needed to keep Carson alive in the database recovered from Michael's lab on M2F-445.

When Dr. Keller fails to report for her morning shift, concerned team members investigate and are shocked by what they discover: Jennifer, unconscious in her quarters -- a mysterious web of tendrils attached to her body. Dr. Beckett suspects her condition may be linked to her research into the Wraith data recovered from Michael's lab.

The beloved doctor leads the medical investigation while Sheppard and company are quarantined under suspicion that they may have been exposed to the same virus that has affected Keller. As Beckett struggles to find a solution, the alien organism grows, creeping out into the adjoining corridors toward the main power conduit. With Atlantis itself now under threat, Woolsey is faced with a decision that could cost Keller her life.

Carson thearizes that the virus is growing keller into a Hive ship, feeding of the ZPM to grow.

With the options looking grave, sending a drone into the building to eliminate the threat seems the most preferable option to Woolsey, but he decides to allow Ronon to take the cure Carson Beckett developed and fight his way through the web of tendrils. He is tied up by the web that using half of Keller's brain quickly identifys him as a threat. Sheppard decides to ram a Puddle Jumper through the mass to reach the isolation room where Keller is being held. He manages to inject the cure into Keller and the mass of webs die as Ronon is released, but he lost the ability to speek for 4 days. Sheppard adds the line at the end "Wonder if anyone'll notice."
