Looks like your buddy outgrew his space because he chopped the tip to make a new clone.
I get a lot of free clones this way from a friend of mine.
He chops the tip, then over waters before giving them away. The last batch came with thrips...
I swear sometimes they look like he just sat them outside in the rain.
No biggie, now that I know what's up.
First thing I do is repot, quarantine, and spray with neem oil.
