Sorry, I think this developed into more than I meant it to. It wasn't like a gripe or anything, it was more of a statement that Tiberius didn't have much else to add unless anyone responded to him as I basically took him as far as we discussed. Whether someone responds now or in the next update, if at all, doesn't make any odds to me.
Besides, I liked Sebastian basically ignoring Tiberius, given their slightly fractious interactions. It played nicely into that dynamic.
