Importing here from IRC:
15:16 <~zigdon> I follow X and Y, but not Z
15:16 <~zigdon> Z posts, X replies (I don't see this, #fixreplies)
15:16 <~zigdon> Y replies to X's reply - I do see this, since I follow both
15:16 <~zigdon> but I have no context
15:17 <~zigdon> but given twirssi's auto context fetching, shouldn't it have pulled X's tweet, since it's context I haven't seen?
15:17 <~zigdon> if not... why?
