At the end of the episode, the tardigrade has been transported to the USS Discovery.
Indeed, the following commentator writes:
In this ep, Saru says the shielding of the test lab on the Glenn prohibits using the transporter to retrieve the project materials. yet we see the guest on board at the end
My question is: Why can Discovery transport the tardigrade at the end of the show when at the start the shielding prevented them?
