screenshot of Twitter home page stream fragment showing an @-reply tweet that by default shows a reply-context of the person being replied to with smaller icon, and original text being replied to, same font, just slightly smaller text size for the original tweet, and above that, the immediately previous tweet that was the start of the thread. There's also vertical ellipses and a "View conversation" link that links to the start.
