Take control of it

Lana (thinking): Fine, I will not allow this THING to enter me! I cannot let such passions or emotions influence me at all! Remember what master taught us... Focus on the mind of the plant... Yes, yes I did it...! I can feel its emotions! It means no harm... It is only acting on its instincts... This is how it shows its love... However, direct it may be...! Alright, try to take control of it... Let go of me... Let. go. of. me. plant.

It removes the tentacle from your mouth.

Lana: Yes, good! You are a good plant! Now, put me back on the ground and release me! Slowly...

It follows your commands and lets you go.

Lana: Thank you plant! You had me scared as you approached me, but in the end, I saw you wanted no harm!

You pet its tentacles and it pulls them away, leaving you alone.

Lana: Alright, time to get clothed and get back to the others. I hope I have passed this test just as it was expected!
