Paige first joined the show in Season 1, where she was introduced to fans as the local bakery truck owner and the mother of Christopher Lassiter (Chase Petriw). Paige's lack of a backstory made her a person of interest among the show's characters, and in one scene when she was mistaken for someone named Michelle at Jack's Bar, the townspeople's suspicions of her shady background were all but confirmed.
Beyond that, while conversing with Preacher (Colin Lawrence), she admits that she does not have a bank account and has only ever dealt in cash. This confidence in Preacher leads to his developing feelings for Paige despite being unsure of her true background or current motivations.
Eventually, he stumbles on her driver's license that confirms her name is Michelle, leading him to question her about what's going on and why she switched identities.
It takes some coercion and a whole lot of trust-building, but eventually, Paige explains to Preacher that she had previously been in an abusive relationship with a man named Wes (played by Steve Bacic) and in order to escape, protect herself, and start anew, she left with Christopher and changed her identity to Paige.
Wes didn't take this situation without a fight, however, as he files abduction charges against her for leaving with their son, and he even tracks her down to her current residence.
A fight ensues shortly after, and at one point Paige pushes Wes down the stairs, killing him instantly. Preacher, who is now inexplicably tied to Paige through emotion and trust, helps her dispose of Wes's body in the woods and go into hiding with Christopher again.
This was the last fans saw of Paige, until a few weeks later. Christopher shows up at Preacher's house asking for a place to stay. Preacher, recognizing that Paige likely went even further into hiding, agrees.
There have been quite literally no details given about Paige's whereabouts since that instance, and a lot is up in the air when you think about how Preacher is still harboring Christopher at the end of Season 2. Clearly, the tie between him and Paige still exists, leaving the show open for interactions between Preacher or Christopher with Paige in the future.
