Sayyid's not the golf-playing type. Seemed to me that he was in the golf club all morning that specific day for a specific reason, rather than exploring new ways of enjoying life and spending his "settlement money". Sayyid and weapons seems to be a usual coupling under the circumstances hinted, but it's still curious how "prepared" he was, for a day at the club! I'm not sure about who the Italian guy might be but considering that Sayyid's Oceanic reference scared him, he seemed to be related to the Economist. I think the golf-murder scene could be the 3rd in the linear temporality of flash forwards.
