It's very possible that Don is still in jail for "Shane" and that "Shane" himself posted as Don. The hoser doth protest too much, methinks. Could the "Shane" on the icebreaker be the real one and this one a...dare I say it?...a fake??? With Don in jail it would be simple for someone else to assume the identity of "Shane McBride."

I say, let's have DNA testing and sort this out once and for all!

As for "Shane" -- you DO know what the penalties are for identity theft, don't you?
