The Big Bang Theory Season 7 Spoilers: Could we meet Wolowitz's mother?

For the better part of seven seasons, The Big Bang Theory has only let us hear the loud, grating voice of Howard Wolowitz's mother. Perhaps thankfully, we have never actually laid eyes upon the woman, but could that change?

The "Spoiler Chat" column at E! Online reports that fans of the hit CBS sitcom will meet a new character who is closer to Mama Wolowitz than anyone would probably want to get:

"Melissa M.: Am I the only person who loves Howard on The Big Bang Theory?
Nope! Howard's mother loves him unconditionally, and although we've never officially meet Mrs. Wolowitz, she's always been one of our favorite characters. But guess what? All of that could change! In this season's penultimate episode, we'll be introduced to Marta, the woman in charge of tending to Mrs. Wolowitz's each and every need. We're not going to give everything away, but let's just say that by the end of the episode, you'll be writing thank you notes to Marta for what she reveals."

In other TBBT news, the "Spoiler Chat" reported last week that both Penny and Sheldon are in for what are sure to be uncomfortable experiences in the near future:

"Kenny: Have you got anything Big up yourselves? (Talking about Big Bang Theory here, sickos).
Do we ever! The gang is going to the movies. We'll meet a film director who believes he's too much of an artist to be doing a low budget horror movie. Plus, get ready for Kelton, a 'cute-ish' and tattooed dude who runs into Sheldon and Koothrappali."

Any guesses as to what Marta could reveal about Howard's mother that we don't already know? Leave your guesses in the comments below.
