Shelly Donahue

Shelly Donahue is the daughter of Ron and Nancy Donahue and one of Sean Donahue's two younger sisters. She onetime snitches to Nancy when Frankie talks about her being smothering behind her back.

Personality

Shelly appears to be devious and cunning. She is often swindling the Heck family. She blackmailed Frankie to give up her hotel room and play Marco Polo with her in exchange for not telling Nancy what Frankie said about her behind her back. In the end, she broke her promise and told Nancy anyway. She also refused to give back Sue's snowglobe she lost during Yankee Swap unless she parted with most of her plushies.

Trivia

• Although she is credited as being in part two of Forced Family Fun, she never actually appeared in the episode.
• Although she seems to be the younger Donahue sister in later episodes, Shelly seemed to be treated as the older sister in earlier episodes like Siblings.
