I’ve seen some discussion of how it’s a bit unrealistic that Tigh wouldn’t tell Adama about what happened to Ellen. I have something to say regarding that, but let me first ask that everyone be a bit kind as I’m going to relate something a bit personal. (Not that our community here isn’t generally kind — you are — but it’s important to me, so I thought I’d mention it.)
My Father died a few years ago, and it wasn’t in a pretty way. After fighting cancer for a number of years, he was simply caught out — a common cold turned into something untreatable due to the cancer drugs and the chemotherapy, but it didn’t kill him. I did. He’d left word for me to make such a decision if the situation arose. So when it did, the doctors turned to me, and I made what I sincerely hope was the right decision.
Without getting into further gory details, let me just say that it took me a long time to understand what happened that night and how it fits into who I am and what my life is. Consequently, I didn’t talk to others about it for quite some time.
Obviously what happened to me isn’t what happened to Tigh. I didn’t poison my Father, I simply allowed him to die — in a situation where he couldn’t have possibly recovered to any state that’d be acceptable to him. Tigh’s situation must be thousands of times worse. So I could certainly understand his reaction.
For what it’s worth, it’s this kind of personal connection that often draws me into the show; when Adama and Lee (or Adama and Starbuck) sit together, when Tigh fights his demons, and even when Baltar tries to grasp the enormity of what he’s done — I see a little bit of myself and my situations and it touches me that much more.
