Meredith Woerner Deputy Editor, Variety.com The official trailer for the second season of “The Summer I Turned Pretty” features two very emotional moments for romance lovers everywhere: One, Jeremiah confronting Belly about their tangled love triangle with Conrad (Christopher Briney). And two, the first sneak peek of “Back to December (Taylor’s Version)” from the soon-to-be released “Speak Now (Taylor’s Version).” “Belly, you were my best friend, we hooked up, and then you hooked up with my brother,” says Gavin Casalegno (Jeremiah) to a distraught Lola Tung (Isabel “Belly” Conklin) in the new footage. “And everybody asked me to act like I was fine, and I wasn’t.”
