Good end

The Big Bang Theory should end with Leonard marrying Priya and Penny realizing that she’s been in love with Raj the whole time. She dated Leonard as an attempt to break her cycle of dating pushy alpha male types while desiring a gentle, quiet partner who would listen to her for once, but Leonard wasn’t a viable option. The meek Raj allows her to take control and have no concerns over infidelity as with past partners, at least when sober. To ensure that he never regains his drunken confidence, the two convert to Mormonism at their wedding.
