I'm with you on that.
In "good" ending it feels like he is treated like a joke at the docks (really with I could punch Gale), Tav just standing there looking at the love of HER life running for HIS life. I mean, come on, let her run after him or cover him or do something productive. Then if you're lucky and you actually get the conversation after that, the options provided are very lackluster and he has very little to say.
The "bad" ending is no better with the dialogue options provided. For the game that prides itself on a variety of choices, in reality there aren't that many that matter or acknowledged afterwards.
The epilogue as a whole stinks, how lazy is it that after 90+ hours of playing you get just a few minutes of closure? I don't know, add some slides at the end if you can't manage anything better. Very disappointing.
