On tonight’s Big Bang Theory Sheldon and Amy reveal that they are going to be taking a big step in their relationship since they have been together so long. They are getting a turtle! They feel that having a joint pet is a big thing for them. Also, a turtle is ideal because they don’t shed and Sheldon can outrun it.
At the pet store, Amy and Sheldon explain to the turtle that he will stay with Sheldon. That is when Sheldon isn’t away for work or at Comic Con. Sheldon also adds that he will also stay with Amy if his application to colonize Mars is accepted. This upsets Amy that he couldn’t bother to tell her.
Amy and Sheldon head back to the apartment without a turtle. Sheldon decided he doesn’t want a wild animal in the house after he played “got your nose” and got bit. Amy is still upset that Sheldon filled out the application. Amy asks him why he wants to go. Sheldon shows her the video submission he made, but this just makes Amy leave. She said she thought the two of them planning to get a turtle meant something and that they would be planning their future together. Sheldon asks Amy to come with him to Mars. She gets excited and points out they could procreate and their kids will be Martians. This pleases Sheldon as well.
In the meantime, Leonard gives Penny a gift that he got her at “the dirty store.” What he purchased is a kit where you cover yourself with body paint and then get on a canvas, do your thing, and “make art.”
After making the art, they find that all the paint is in one spot. They don’t understand why they were out of breath. They decide that they need to try again. This leads to Leonard getting paint in his eyes because Penny wouldn’t let him wear safety goggles. They did manage to make a better painting, but Penny doesn’t want to hang it up anywhere She suggests that they give it to Sheldon and tell him William Shatner painted it.
As for Raj, he is spending the night at Emily’s apartment. He inquires as to where her roommate is. Emily jokes about having killed her so they can be alone more. This makes Raj feel unsettled since she won’t say that she is just kidding. Emily gets called into work, so Raj stays and waits for her. He calls Howard who is playing video games while Bernadette does the taxes. Raj decides to snoop around Emily’s apartment and accidently breaks the drawer in her nightstand. Howard tries to give him suggestions on how to fix it. This fails and Emily comes home. Raj confesses while Bernadette and Howard listen through the phone that Raj didn’t disconnect.
Emily ends up forgiving Raj but then gets worried and asks him if he looked in her closet. Raj says he did not, but wonders what she is hiding in there. She tells him not to worry about it before rolling over and going to bed. This again makes Raj feel unsettled.
