I've been diving for a year and I understand and can relate to thinking about different scenarios as a new diver. I would echo what everyone is saying, don't add a disconnect, instead invest in a good setup and provide good maintenance on your gear.
As for freeflows, while air does quickly escape, keep a cool head, end the dive and ascend. I've read somewhere that with freeflows you can lose air at 100-200psi per minute, depending on gear and other circumstances. At that rate you should be able to ascend OR reach your buddies octo before you are completely out of air.
Next, dive as much as possible, the more you dive the more experience you get and the more confidence you'll have. With that in mind take a few moments in each dive to practice a skill. Happy diving!
