>>83621828There's kind of 2. One is Ronnie Anne, who wasn't seen in Heavy Meddle but will be shown more later on, particularly in Save the Date when she's Lincoln's date in a double date with Lori and Bobby.
Then there's Christina who Lincoln pretended flirting and making out with in Making the Case and Luna tried to set her up with him in Fro Bros About to Rock. She doesn't have any lines.
And a future episode synopsis says that Lincoln's sisters will set him up with 4 dates for an upcoming Sadie Hawkins dance, meaning at least 2 more potential love interests.
Goddamn, even without the sisters this is becoming a harem series.
