Interviews really are the best.. the actors always let a few spoilers slip and whether intentional or not, spoilers are spoilers and we can’t ever get enough of them! Check out what he has to say about what’s coming up on this season of 90210!
On what’s coming up for Liam next season…
Lanter spills the deets about Liam and Annie: he says that their relationship will “blossom into a romantic relationship” and within a couple of episodes into the new season, the two will share their first kiss on “another boat that wasn’t blown up by creepy Jasper.” On a different note, Lanter points out the biggest shocker: Liam has a half brother coming.
On what’s become of Jasper…
Unfortunately we have no official word on what’s happened to Jasper. Lanter says that they’re already “few episodes in and they haven’t explained last season.”
On whether the fact that Liam’s the one who’s coming out of the closet…
Although Liam is involved with Annie, Lanter thinks that with them only being a few episodes in, “there’s a possibility of it heading toward any of the three guys”
