He hates being Palpatine's puppet. For a long time he thought he would do anything to get rid of his Master's grasp on him. Now that he's actually put in front of the chance to do so, he's not sure he would be able to accept Obi-Wan's deal and be done with it all. Not without being aware of every little detail, not if rushing meant risking to end up stuck in something way worse. Knowledge is power, or so his Master liked to repeat on and on. Better the devil you know and all that shit, right? But Obi-Wan is so gentle with him, and he's answering all of his questions... Should he trust him? Could he really trust a literal devil over his monster of a Master? (Or, Anakin accidentally summons a demi-devil. Obi-Wan is just happy to help.)
