Lolly Lavigne/Current timeline

Lolly Lavigne is Becca Brady's best friend.

History
At one point, she and Becca's brother, Jamie Brady, secretly began hooking up.

After Becca tells her that she has come from the future, Lolly is deeply troubled when she finds out that not only did she break Jamie's heart in that future, but they have become estranged and have not spoken for ten years prior to Becca and Andy's wedding. She continues to be bothered, especially when Becca constantly refuses to tell her the reason they ended their friendship. Becca explains that she doesn't want to tell her because she's not sure if she can still prevent it from happening this time around.

While she initially continued to pester Becca about things that transpired between them in the future, she finally agreed to stop trying, on the condition that Becca do her best to prevent it from happening again. The duo hopes that nothing is predetermined, and that they can stop their friendship, as well as Lolly's relationship with Jamie, from going bad.

However, Becca did agree to tell her what happened with Jamie after she allegedly broke his heart—Jamie had to go to rehab several times for his drug abuse problems. Because of this, Lolly became deeply concerned for Jamie's current state, and it began interfering with their current relationship, thus making Lolly learn the hard way how complicated it is to know some things ahead of time.

Personality
Lolly has a carefree spirit.
