Teegan Walker is a demanding ZBZ Nationals representative and member of the Grand Council.
Season 1[]
Her first appearance is that of someone from nationals to check in on the sorority after Jen K's article. After Frannie tried to snow her, Casey, trying to save the sorority, meets up away from ZBZ to talk. Afterwards, Teegan replaces Frannie with Casey.
Season 2[]
In the season premiere, she returns after Rebecca began acting out. She admits to having "eyes and ears everywhere" so she knew about Rebecca's fountain incident and rage during the powder puff game. Despite Rebecca having already been punished, she wanted more of a punishment for Rebecca, including expulsion from the sorority. (Brothers and Sisters)
In a later episode in the season, she is among the guests at the ZBZ National Conference. Casey watched as Teegan treated Lizzi poorly and told her that she would deny Frannie's request if Casey would get rid of Lizzi. However yet again, Casey didn't do as she asked. She then revealed that Frannie was the one who called her during Greek Week. (See you next time, Sisters)
