In the climactic scene, Abhilash's character (played by Chandu Salim Kumar) unexpectedly appears and exclaims, "Loose adikkada" (which translates to "Pull it loose"). However, this is a glaring mistake in the script because Chandu was not present during the rescue operation and couldn't possibly know that the coir was stuck between the rocks.
When Subhash falls onto the last ledge, his body is able to hold onto the ledge even in such a state. However, when Suji gets down to rescue him, it is noticed that the ledge was very slippery. Therefore, there was no way that Subhash could have stayed on the ledge in that angle for long, which would've caused him to slip down further.
