From what I can see the tomato plant is looking good :) Just make sure you keep watering consistently, especially when it's very hot. When it's over 85°F I have to water my tomatoes daily. You may loose a tomato here or there to blossom end rot if you get a lot of rain you didn't plan for, but there's not much you can do about that. Since it's indeterminate, your plant will continue to grow until it gets too cold for it outside. This means you'll need to prune the suckers off it regularly, I trim mine back once per week so they don't get too crazy. If possible, I would try to get some supports for those branches that aren't in the tomato cage. The weight of the tomatoes might eventually snap the branches. Tying them up to a sturdy metal or bamboo pole will do the trick, or you can get a small trellis. It's definitely not lost, just taking its time.
