Halley Wolowitz's arrival in "The Big Bang Theory" family came in a blast as Amy celebrates her birthday, the winter finale of the popular TV series "The Birthday Synchronicity" features a very historic moment for the nerdy bunch. The long wait is over and finally, Bernadette has safely delivered her first born with Howard and the events were just as funny and nostalgic at the same time. The Wolowitz baby will tribute Howard's mother by doing voice overs, Halley seemingly the same as her grandmother's voice, hilarious.

The last episode of "The Big Bang Theory" makes a momentum shift in a report from Hollywood Reporter when Howard and Bernadette's baby arrived, but the scenes traversed from the usual hospital scene to the preparation of Amy's birthday. As Sheldon and Amy try to make out as a birthday celebration so as the married pair Leonard and Penny seemed to be in the same boat. Meanwhile, the surprise new parents found out their newborn is a girl in contrast to all their predictions and preparations as Halley, named after a comet, was quickly spoiled by everyone especially by the ever despotic Raj.

According to a report from International Business Times, the series' showrunner, Steve Molaro is already enjoying the idea that Mrs. Wolowitz memory will still be included in the show, to add up to his relief that a baby's appearance will not be needed always. Halley's special cry which turned out to be the same with Howard's mother will be voice by Better Things star Pamela Adlon, who is also a dear friend of the late Carol Ann Susi, the original voice of Mrs. Wolowitz. The unexpected loss of their cast has deeply saddened the whole family of "The Big Bang Theory" and Halley's arrival will surely bring back the comical attitude of Howard's mother.

"The Big Bang Theory" Season 10 Episode 12 titled "The Holiday Summation" will air in January featuring Howard and Bernadette's struggles and adjustments as a new parent. Howard will be missing out some days at work to help out Bernadette on taking care of baby Halley, who seems to cry a lot. Nevertheless, the nerdy bunch will always be there to support each other as they filled the family with love and laughter.
