[Pro Sniper]

Hardly surprising is it. Lewis is clearly the type of person who does someone a favour and then brings it up at every turn. Any act of good will from such types inevitably begins to smell of selfishness.

Obviously he sees this friendship with Cam(which is as real as Sian's diddies) as his winning ticket. That's why he went nuts the other night when he felt his "selfless act" might have dimmed. He's reminding his "friend" and all the gullible mugs out there of the pay off he expects in return. This is just the way all self-absorbed people operate.
