It looks like one of many things, but my gut feeling is that it's Pegler's Aloe. But distichous and blue and small is tough to ID at this point. ETA-you'll pardon me for saying so, especially if the rest of your Aloes are fine and dandy, but that rich looks kind of rich for a young plant (or an older one, for that matter). Was it just watered? I really hate losing any Aloe, and an A. peglerae is almost the worst (thankfully, fairly easy to replace), since it's such a pretty aloe. Pic courtesy of Ernesto Sandoval. And here are several in habitat - thanks for the photo by Riaan L.

Weigela was my first though as well........and there are a number of cultivars with gold foliage and red flowers. However it is too indistinct and distant to confirm that ID.

According to Encyclopedia of Perennials (2006, Dorling Kindersley, London) when compared to S. officinalis the S. monieri is a rarely seen, noticeably shorter-growing plant with longer flowers. And 'Hummelo' and 'Rosea' are both cultivars of S. officinalis.

That looks a lot like my Brandywine viburnum(Viburnum nudum). The browning could be from lack of water. It looks like a young plant, not fully established, so removing the grass/weeds around it and mulching would probably be helpful.
