Just keep telling them that you're focusing on now, and doing what's right for the company in the meantime. Because that's what's actually important. The future of the company remains secure, and that everyone has the company's best interest at heart while your father makes his recovery. Emphasis on him making a recovery, as that is what everyone wants to be his first priority. Anyone on the board giving you trouble, or holding back the above mentioned progress wouldn't dare go so far as to disagree with that. If they do, they're only hurting the company as a whole.
As for the Bat, that doesn't concern you, your father or your company. I know they will keep trying to make it about you, but it's obvious neither of you had anything to do with it. It's best to brush the Bat off as old news for Thomas Inc, yourself and Mr. Brandon. You're focusing on the company, he's focusing on getting well. Business as usual after what could have been a pointless tragedy.
I am, I wish I could say the same for Georgia, but I figure I'll take her babysitter to task for that one. ;-)
Luke, call me if you need anything at all. I'm seriously only a phone call away, if it's an emergency I'm only a few doors away.
