'Pretty Little Liars' 'Out of the Frying Pan, Into the Inferno': Spencer withdraws from the Liars

Check out these sneak peek clips of the next "Pretty Little Liars" episode, titled "Out of the Frying Pan, Into the Inferno." First, Spencer hasn't told the girls about Toby and what she has found out about him. She definitely seems to be withdrawing into herself, but hopefully she'll come clean soon. Liars gotta stick together with the "A" business.

Meanwhile, Emily's bio notebook appears to have a conversation written in it between Alison and someone whose handwriting they sort-of recognize. And Ali is talking about Toby to this said someone. Dun dun dun.

Finally, Emily shows Spencer the written conversation, which mentions a "beach hottie" that Ali was involved with and possibly scared of. But Spencer's pretty much over it.

Do you think this is just the start of Spencer's downward spiral? Is she going to tell the Liars about Toby?

"Pretty Little Liars" airs Tuesday nights at 8 p.m. ET/PT on ABC Family.
