Mystery plant

Months ago, or maybe even last year, a mystery plant started growing in the same big pot as a bunch of Thai chillies. I guessed it might be a weed of some sort but left it anyway as I was curious what was growing. Usually I will pull it out once it’s identified as an unwanted weed. As this grew, it developed leaves that seemed rather familiar although I couldn’t identify them. I figured it might die out as some point but it’s still growing and has now started upward growth. It’s not yet a meter tall but I believe it won’t be long until it reaches that point. And still I couldn’t work out what it was.

But while I was at the hardware store’s garden department, I happened to see a plant that looked very similar and I think I have worked out the mystery. It seems we have a fig tree or something related growing out back. I can’t imagine we got any sort of seed into our backyard as we don’t eat figs. My best guess it has been dropped by a bird passing through.
