The second ep of Season 6 is coming up tomorrow at 7 pm on CBC.
"Ty struggles to deal with the fact that Amy has found the engagement ring and has to decide how... or if... he is going to propose to her. The episode then turns into a comedy of errors as Lou and Jack are both aware of Ty's intentions but Amy doesn't have a clue that they are. And Tim is... well, clueless about the whole matter, which you can imagine is not going to go over well with him."
