Betrayal or loyalty

The Gladers have made contact with a group of Cranks in the ruins of the building , luckily these Cranks are not too far gone, meaning they are nor crazy YET. These people are desperate for a cure and will do anything to get it. Which gave the idea to Thomas to use them to get through the city. Most of the Cranks refuse but the leader and a female Crank named Brenda join up to help them. When they went to the underground where the Cranks store the food a huge explosion was heard from above and made the under ground tunnels collapse. The group got separated leaving Thomas and Brenda alone. As they keep walking through the obscure tunnels Thomas realizes that this girl Brenda is a very touchy feely girl, since she is always hugging him and often holding his hand and he barely knows her. They walked for several hours and trouble arises since they encounter a group of nose-less Cranks . Eventually the escape them and exit the underground but the realize it is night time so they decided to get some rest on a parked truck outside in an ally. The next morning Thomas wakes up with a disturbing message next to him. It said "Thomas you are the real leader" then he realized that thanks to that message the cranks wanted to help them since they thought he is somewhat special. As they were leaving the truck they heard drums faraway in the distance and went to investigate, it turned out to be a Crank party and when they were just about to leave they got caught and since they knew he was Thomas they didn't did anything to him. Instead the forced him to go the party. Thomas felt weird being in a party full of insane Cranks but then Brenda proposed him something unacceptable. He told him that they should stay here with the Cranks since here they were finally safe, here they'll be happy. She confessed to him that during the spread of the Flare wicked had no cure and it still has no cure. So why travel to the "Safe Haven" where the supposed "Cure" is. Everything they've done is a lie, there is no cure. 
Should he stay here and abandon his fellow Gladers to the city and have a save life or leave all of them behind and travel to save haven.  


During the long dark walk on the "Underground" I found the first clue that Brenda is probably going to hurt Thomas. 
"Thomas let go of her, leaned his head back against the wall. She pressed in again and wrapped her arms around his middle. 'Uh...Brenda?' he asked."(pg 175)
Who hugs and gets all touchy with someone who just met? maybe there is a purpose for all of this actions. Brenda wants to use Thomas for something. Why is she so desperate to get his attention what is it that Brenda wants so bad from him? The cure? Safety? Resources?. She is planning to do something to him.

This is a follow up quote that shows Thomas will not fall on Brenda's hands.
"Thomas was enjoying her being so close, but it seemed so bizarre and out of the blue. Then a surge of guilt, thinking of Teresa. All of this was stupid. He was in the middle of a brutal and ruthless attempt to make it across  the wasteland, his life on the line, his friends maybe dead. Teresa could even be dead. To sit here and cuddle with some strange girl in the dark was about the most absurd thing he could think of." (pg 174)
The author is trying to tell that even though of the situation Thomas is  still a rational person who thinks and analyses what is happening and why is it happening. So Thomas will pretty much keep his distance with this girl not only for his safety but for his sense of guilt toward the fellow Gladers and specially towards Teresa


I have to possibilities, one Brenda is actually in love with Thomas and wants to stay with him no matter what, but this is not likely since she made Thomas promised to no matter what to take her to WICKED were the cure is, even if it meant going alone. My second possibility is that Brenda is actually planing on leaving everyone behind and kill some if she has to as long as she gets the Cure. She will use Thomas in every possible way, this is more possible since during the book she admitted that she was loosing control of herself because of the Flare, and she stated that she rather die than turn insane so she is desperate for the cure.
