Brock Lesnar's return to the company that made him a star was short lived, but it did leave WWE fans wanting more. That interest for more of Lesnar, is what makes the sudden departure great booking.
Lesnar came back for a feud with John Cena. They had one match at Extreme Rules in which Cena won, but Lesnar did the most damage. The following night on RAW, Triple H confronted Lesnar and denied him his lofty contract demands. In response, Lesnar attacked him and "broke his arm."
The best part about Lesnar's return, in my opinion, is the return of Paul Heyman. Heyman came out as a legal representative for Lesnar and informed the WWE that Lesnar "quit" and would be suing the WWE. Heyman helps Lesnar, who is not the best on the mic and makes his return all the more better.
Lesnar's abrupt departure leaves the WWE with many different options.
Lesnar could make a surprise return at any time and begun his destruction again. This possibility leaves the WWE Universe trying to predict when he will come back.
The WWE most likely wants Lesnar to play a big role at WrestleMania XXIX. In order for that to happen, he must remain healthy. He will reportedly remain limited in appearances so that he can be involved in the build up of SummerSlam and WrestleMania.
Lesnar is most likely going to take on Triple H at SummerSlam. However, his opponent at WrestleMania XXIX is still unknown.
In the time that Lesnar is being kept healthy and not making too many appearances, he could be waiting for the return of two other superstars. The first being The Rock, who reportedly will return in early 2013.
Lesnar and The Rock have their history and could lead to an interesting feud. Lesnar won the WWE Championship from The Rock in 2002 and became the youngest WWE Champion in history. The youngest champion before Lesnar was The Rock. This could play a role in their feud.
The other superstar that Lesnar could start a feud with when he returns is The Undertaker. The two have been friends behind the scenes, but have also had some heat, which was seen after one of Lesnar's UFC fights.
After the fight the two had a verbal confrontation as Lesnar walked past Undertaker. This match will draw much interest from fans and help the ratings at WrestleMania XXIX.
The Undertaker will also reportedly make a return at RAW's 1,000th episode. We could see the start of this feud as early as the 1,000th episode.
