What is this aroid, i can not find the id for this plant! Here is a link http://www.flickr.com/photos/92745346@N04/
Looks to me like some sort of climbing philodendron and also another plant with more succulent looking leaves - maybe a hoya or dischidia? Whatever the little one is it looks like it has been given too much direct sun and has gotten burned.
If it is a hoya I think I'd separate the two because I think they would need different watering schedules and if that is indeed a philodendron I'd give it a new mix of potting soil mixed with bark or orchid mix or something to help with drainage and a moss pole to climb on.
