Original Commentary
In panel three, originally Tina just mentions (I'm paraphrasing here) "But what I'm trying to say here is, can I have my $50 back?". But I had a few issues with it ending like that. This is our first impression of her that we get. She may be a kind, understanding woman who put up with Peter's easily distractible mind, but all we see is "I want my money back". Which makes her seem not so nice. But Terrence really liked the line and reworked it so we were both happy (or at the least, not annoyed). -Isabel

Modern Commentary
Isabel is right. I like the original joke, but we don't get a lot of screen time for Tina. If this were animated and she had five minutes to get a bit of character across maybe, but she just has a couple panels here - Terrence
