This week's episode of SmackDown is set to take place in Chicago. CM Punk is set to appear on the show, and his wife, AJ Lee, has been heavily rumoured to return. Lee hasn't made a single appearance on WWE programming in nearly a decade.Here are five signs that AJ Lee is returning on this week's SmackDown:#5. Seth Rollins' outburst at Clash in ParisAt Clash in Paris, Seth Rollins defended his World Heavyweight Championship in a Fatal 4-Way match against Jey Uso, LA Knight, and CM Punk. During the match, Seth started trash-talking to Punk.Seth said that he hates Punk's family and wants him to go away. This might have been a subtle hint that Punk's family will also get involved in this feud going forward. Lee could mention this in her promo if she returns.#4. Becky Lynch attacked CM Punk on RAWOn RAW this week, CM Punk came out to confront Seth Rollins after his loss at Clash in Paris. Rollins' theme song started playing, but Becky came out instead. She made fun of Punk and even slapped him around before he finally left the ring.Punk didn't hit Becky or harm her in any way. However, he said that she will regret doing this to him. Punk might be hinting towards AJ's return since he can't hit Becky, but she can.#3. SmackDown is in ChicagoThis week's episode of SmackDown is set to take place in Chicago, which is CM Punk's hometown. When CM Punk made his return to WWE back at Survivor Series 2023, the event was also held in Chicago.It would only make sense if Punk's wife made her long-awaited WWE return in the same town as he did. The moment would be very poetic if she returned in Chicago on this week's SmackDown. Punk also confirmed that he will be on this week's show during a backstage segment on RAW.#2.
